## How to Find Volume

Volume is the measure of 3-dimensional space that a geometric shape or object occupies. It’s measured in cubic units, such as cubic yards or cubic feet.

Of course, you can find volume easily using a calculator like the one above, but you can also find it yourself using a formula. Read on to learn more about how to calculate it.

## Volume Formulas

The volume of every shape is calculated differently using a different formula. Use the formulas below to find the volume of several three-dimensional shapes. ### Volume of a Cube

V = a3

a = edge a length ### Volume of a Rectangular Prism

V = l × w × h

l = length
w = width
h = height ### Volume of a Sphere

V = 4 / 3πr3 ### Volume of a Cylinder

V = πr2h

h = height ### Volume of a Cone

V = 1 / 3πr2h

h = height ### Volume of a Pyramid

V = 1 / 3e2h

e = edge length
h = height ### Volume of a Triangular Prism

s = 1/2(a + b + c)
V = h × s(s – a)(s – b)(s – c))

a, b & c = triangle sides

h = height ### Volume of a Capsule

V = πr2h + 4 / 3πr3

h = height ### Volume of a Hemisphere

V = 2 / 3πr3 ### Volume of a Spherical Cap

V = π / 6h(3r2 + h2)

h = height ## How to Find the Volume of an Irregular Object

The formulas above can be used to calculate regular objects with a defined formula, but many objects are irregular or have no obvious formula. Water displacement is a technique used to find the amount of space an irregular object consumes.

The water displacement technique involves filling a container with water and measuring the amount of water displaced by submerging the irregular object in the water in the container.

For example, fill a container with water and calculate the volume of the water using the formulas above.

Submerge the irregular object in the water and observe that the water level in the container has risen.

Measure the amount of water as before and calculate the volume of the water with the object submerged.

Subtract the initial result by the result after the irregular object was placed in the water to find the volume of the object.

### Measuring Volume Using Weight

In some cases, you can measure the volume of a fluid or irregular solid material by measuring its mass. If you know the density of the material, you can calculate the volume using its mass with the following formula:

V = m / ρ

where:
V = volume
m = mass
ρ = density

The volume of a material is equal to the mass m divided by its density ρ.

This technique is commonly used to estimate the volume of materials like gravel or water.

## Volume Measurement Tips

One important consideration when measuring is to take all measurements using the same unit of measure. If your measurements are in different units, convert each measurement to the unit you want the results in.

Use our length converter to convert your measurements to a consistent unit. You can also use our volume converter to convert your result to another unit of measure.
