Question

An Aquarium’s dimensions are 3 1/4 ft x 2 ft x 1 3/4. What is the volume of the Aquarium?

Answer 1

11 3/8 ft^3

Explanation:

The volume is given by

V = l*w*h

V = 3 1/4 * 2 * 1 3/4

Change the number to improper fractions

V = (4*3+1)/4 *2 * (4*1+3)/4

= 13/4 *2* 7/4

Rewriting

= 13/1 * 2/4 * 7/4

= 13/1 * 1/2 *7/4

= 91/8

Changing back to a mixed number

8 goes into 91 11 times with 3 left over

11 3/8 ft^3

Answer 2

Volume = length x width x height

Volume = 3 1/4 x 2 x 1 3/4 = 11 3/8 cubic feet
