## How to Find the Volume of a Regular Object or Geometric Shape

Volume is the measure of 3-dimensional space that a geometric shape or object occupies and is measured in cubic units, such as cubic inches or gallons. Use the formulas below to find the volume of many different geometric shapes.

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 unit conversion calculators to convert your measurements to a consistent unit. You can also use our volume unit conversion calculator to convert your result to another unit of measurement.

Check out our surface area calculator to find the surface area of these geometric shapes.

### Cube

cube volume = e3

e = edge length

### Rectangular Prism

prism volume = lwh

l = length
w = width
h = height

Calculate rectangular prism volume

### Sphere

sphere volume = 4/3πr3

Calculate sphere volume

### Cylinder

cylinder volume = πr2h

h = height

Calculate cylinder volume

### Cone

cone volume = 1/3πr2h

h = height

Calculate cone volume

### Pyramid

pyramid volume = 1/3e2h

e = edge length
h = height

Calculate pyramid volume

### Capsule

capsule volume = πr2h + 4/3πr3

h = height

Calculate capsule volume

### Cap

cap volume = π/6h(3r2 + h2)

h = height

Calculate cap volume

## How to Find the Volume of an Irregular Object

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