HELP PLEASE

A fish tank has dimensions 3 ft by 2 feet by 1.5 ft. two feet is the height of the aquarium. If the tank is not filled all the way and there are two inches of empty space at the top, how many cubic inches of water are in the tank?

Answer 1

The right answer is: 14,256 cubic inches

Explanation:

First of all, let's identify the dimensions of the tank and convert them to inches

Knowing that 1 Feet = 12 inches

So, the dimensions of the tank, expresed in inches will be:

Height (H): 2 ft. x 12 = 24 inches

Width (W): 1.50 ft. x 12 = 18 inches

Lenght (L): 3 ft. x 12 = 36 inches

Before calculating the volume of water inside the thank, We must consider that there are two inches of empty space at the top.

So , We must substract 2 inches to the height to calculate the volume.

Then, the height used for calculating the volume will be:

H'= 24 inches - 2 inches = 22 inches

Then,

Volume (V)= W x L x H'

V= (18 inches) x (36 inches) x (22 inches)

V= 14,256 cubic inches
