Question

An aquarium shaped like a rectangular prism has a length of 24 inches, a width of 12 inches and a height of 18 inches. You fill the aquarium half full of water. When you submerge a rock in the aquarium, the water level rises 0.5 inch. Find the volume of the rock

Answer 1

The volume of water rises 0.5 inches, so we can use that as the height of the water.

Volume = Length x width x height:

Length is given as 24, width is given as 12

The volume of the rock = 24 x 12 x 0.5 = 144 cubic inches.
