Question

An aquarium has a length of 20 inches, a width of 10 inches, and a height of 18 inches. The directions tell you to fill the aquarium until you have a 2-inch gap between the top of the water level and the top of the aquarium. What is the volume of the water?

3,200 in. 3
2,304 in. 3
3,600 in. 3
400 in. 3

Answer 1

Water depth = 18 − 2 = 16 in.
Volume = length × width × depth = 20 × 10 × 16 = 3,200 in.^3.
