What does volume equal

You'll find detailed instructions on the wikihow page. Check out the measures connected to your lung capacity by using a device called spirometer. In chemistry, a gas syringe is used to insert or withdraw a volume of a gas from a closed system. This laboratory glassware can also be used to measure the volume of gas evolved from a chemical reaction. Find the volume of the gas, given its density and mass.

Calculate the volume of a compressed gas in a cylinder applying ideal gas equation. You can't calculate a volume of a rectangle , a volume of a circle or a volume of a square because they are 2-dimensional geometric figures.

As such, a rectangle does not have a volume but it does have an area. What you're probably looking for is the volume of a rectangular cuboid or, in more common terms, you want to find the volume of a box , which is a 3-dimensional object.

To find the volume of a box, simply multiply length, width, and height — and you're good to go! For dimensions that are relatively small whole numbers, calculating volume by hand is easy. For larger or decimal valued numbers, the use of the volume calculator is very efficient.

There are many applications in real life where the volume calculator is useful. One such instance is in road or pavement construction, where slabs of concrete must be built. Generally, concrete slabs are rectangular solids, so the concrete calculator — which is an application of the volume calculator — can be used.

Also, the volume formulas may be helpful if you are a keen gardener or just a happy owner of a house with a yard. Check out our awesome tools such as:. Mulch calculator to find the amount of mulch needed for your garden project. Soil calculator and potting soil calculator to estimate the volume and cost of topsoil, as well as the amount of soil needed for your flower-pot. Gravel calculator which can help in planning a gravel driveway construction.

Sand and paver sand to help you with the calculations on the building site. Moreover, you can meet volume in your kitchen or bathroom: any liquid we drink e. Another related application, although slightly different, is the concept of surface area. Suppose the entire exterior of a building must be painted.

To know how much paint must be purchased, the surface area of the building must be calculated. The convenient to use surface area calculator will calculate this for you. The volume formula depends on the shape of the object.

One of the most popular shapes is a rectangular prism, also known as a box, where you can simply multiply length times width times height to find its volume.

For other 3D shapes, check Omni's Volume Calculator. Measuring the volume depends on your object's state of matter. For gases, to roughly measure the volume, you can inflate a balloon and use it to displace the water in a graduate cylinder. A similar method works for solids — put the object into a graduated container and measure the change in reading.

Volume is "cubed" , as it's a three-dimensional measure. Area is a "squared" value, as the area of a shape covers two dimensions.

You can remember that volume is a cubed value by recalling a few volume unit names, such as cubic meters , cubic feet or cubic yards. A cubic meter is the SI volume unit. However, as it's quite impractical, most often you will encounter volume expressed in:.

Graduated cylinders and Erlenmeyer flasks will work if you need to roughly measure the volume of a liquid. For more precise measurements, you need to use a volumetric pipette and burette. However, if you're baking a cake or prepare a delicious dish and the recipe uses volume units, you can simply use a measuring cup, glass or spoon.

The cubic meter m 3 is the SI unit of volume. It is derived from the base SI unit of length — the meter. Although the cubic meter is the basic SI unit, other units are used more often: for the metric system milliliters, liters, or cubic centimeters are popular choices, while for the Imperial system you can find volume expressed in pints, gallons, cubic inches, cubic feet or cubic yards. Volume is an extensive property , the same as the amount of substance, mass, energy, or entropy.

An extensive property is a measure that depends on the amount of matter. A volume is a 3D measure , while surface area is two-dimensional. The volume tells us about the cubic space that an object occupies, and the surface area is the sum of all areas forming the 3D shape.

You can use the fluid displacement method for the irregular shaped solid objects:. The volume measures the amount of space taken up by an object in three dimensions. Another closely related term is capacity, which is the volume of the interior of the object. In other words, the capacity describes how much the container can hold water, gas, etc. The volume of the Earth is approximately equal to 1. To calculate the surface area to volume ratio SA:V, you simply divide the surface area by volume.

For some chosen shapes:. Embed Share via. Table of contents: What is volume? A cube is a special case of a cuboid where all three sides are equal in measure. Observe the following figure to see the equal sides of a cube and the space it occupies.

Just as we built up a cuboid using rectangles, we can build a cylinder using circles of the same size. A cylinder is a tube-like structure with two parallel circular bases which are joined by a curved surface at a fixed distance from the center. The distance between these two bases is the height of the cylinder. Pyramids have a polygon as their base and triangular faces that meet at the apex. The difference between a cone and a pyramid is that the base of a cone is circular whereas the base of a pyramid is a polygon.

Given below is a detailed tabular list of volume formulas in a nutshell describing volume formulas for all the possible 3-D solid shapes. Example: Find the volume of a right circular cylinder of radius 25 m and height 1 meter. The volume of a cylinder is The S. However, the most commonly used unit for volume is liter.

Apart from this, large and small volumes are measured in other units like milliliter ml , pints, gallons, and others. The following table shows a few units related to volume and its metric equivalents.

While the US standard unit is a cubic yard or cubic inch, the more widely used units are gallons, pints, or fluid ounces. The following table shows a few of these units and their equivalent metric conversions. The volume calculator helps to calculate the volume of any given shape quickly and easily. Volume is a branch of mathematics that deals with measuring the capacity of different solid shapes. Try Cuemath volume calculator now. It is an online tool available for easy and fast calculations.

Example 1: Edwin has a conical vessel with a radius of 6 inches and a height of 7 inches. What is the volume of the vessel? The vessel is in the shape of a cone. Example 2: Joe loves playing with building blocks. He built a structure with 15 cubes. If the length edge of each cube is 3 inches, what would be the volume of his structure?

Refer back to our page Calculating Area if you cannot remember how to calculate the area of a circle or triangle. You may be wondering how you could work out the radius of a ball.

Short of sticking a knitting needle through it effective, but terminal for the ball! You can measure the distance around the widest point of the sphere directly, for example, with a tape measure. This circle is the circumference and has the same radius as the sphere itself.

Just as you can calculate the area of irregular two-dimensional shapes by breaking them down into regular ones, you can do the same to calculate the volume of irregular solids.

Just split the solid up into smaller parts until you reach only polyhedrons that you can work with easily. In this example the radius is 20cm half the diameter. Because the top is hemispherical, its volume will be half that of a full sphere. The volume of this section of the shape therefore:. The total volume of this water container is therefore: , This is quite a large number, so you may prefer to convert it to However, it is quite correct to express it as cm 3 since the problem does not ask for the answer to be expressed in any particular form.
