# Volume of a Right Prism

How to find the volume of a right prism: formula, examples, and their solutions.

## Formula

*V* = *Bh**V*: volume of a right prism*B*: base area*h*: height of the prism

## Example 1

To use the formula,

find *B* and *h*.*B* = 7⋅3 = 21

Area of a rectangle*h* = 8

*B* = 21, *h* = 8*V* = 21⋅8

## Example 2

To use the formula,

find *B* and *h*.*B* = (√3/4)⋅4^{2} = 4√3

Area of an equilateral triangle*h* = 7

*B* = 4√3, *h* = 7*V* = 4√3⋅7

## Example 3

Roughly draw the prism.

Write the edges: 11, 5, and 3.

To use the formula,

find *B* and *h*.*B* = 11⋅5 = 55*h* = 3

*B* = 55, *h* = 3*V* = 55⋅3
