Question

A rectangular fish tank contains 3,240 cubic inches of water. The dimensions of the base of the fish tank are 12 inches x 18 inches. How tall is the fish tank?

Answer 1

Volume = length x Base x height

3240 = 18 x 12 x H

3240 = 216 x H

H = 3240 / 216 = 15 inches

Answer 2

fish tank is 14.87 ≈ 15 inches tall.

Explanation:

Given : A rectangular fish tank contains 3,240 cubic inches of water. The dimensions of the base of the fish tank are 12 inches x 18 inches.

To find : How tall is the fish tank.

Solution : We have given that volume of fish tank = 3240 cubic inches.

Length of tank = 12 inches.

Width of tank = 18 inches .

Volume of rectangular tank = length * width * height

3240 = 12 * 18* height .

3240 = 216 * height.

On dividing both side by 216 and switching the sides .

Height =
`(3240)/(216)` .

Height = 14.87 inches

Therefore, fish tank is 14.87 ≈ 15 inches tall.
