VOLUME OF A CUBE

VOLUME OF A CUBE

DEFINITION:

Volume - the amount of space occupied by a three-dimensional object as measured in cubic units.

Illustration:

Formula:

V = S * S * S = S³

where:

S = side

Problems:

1. Find the volume of a cube whose side measures 2 meters.

Given:

S = 2 meters.

Required: Volume

Solution:

V = S * S * S = S³
     = 2 m * 2 m * 2 m

    = 8 cubic meters; final answer

2. What is the volume of a cube whose one side measures 3 feet?

Given:

S = 3 ft..

Required: Volume

Solution:

V = S * S * S = S³

   =3 ft. 3 ft. 3 ft. 

    = 27 cubic feet; final answer

3.The side of a cube has a measure of 4 inches. What is its dimension?

Given:

S = 4 in.

Required: Volume

Solution:

V = S * S * S = S³

   = 4 in. * 4 in. * 4 in. 

    = 64 cubic inch; final answer
