Finding the Volume of a Rectangular Prism

A Rectangular Prism looks like a box and has a
3-dimensional (3D) shape.

The formulas for volume of a Rectangular Prism is
v = l * w * h  or  v = b * h

v is the volume
l is the length of the base.
w is the width of its base.
h is the height
b is the area of its base

 

Example: find the volume of the Rectangular Prism

volume of a rectangular prism

Formulas is v = L * w * h
l = 6 cm
w = 4 cm
h = 5 cm
v = 6 * 4 * 5 = 120 cm

 

You can find the volume of a prism by counting  
unite cubes.
Example: the volume of this prism is 20 cubic centimeter (cm).

There are two layer with 10 cubes in each layer. The
volume is 20 cubic centimeter or 20 cm
