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

Answer:

fish tank is 14.87 ≈ 15  inches tall.

Step-by-step 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 = $\frac{3240}{216}$ .

Height =  14.87 inches  

Therefore,  fish tank is 14.87 ≈ 15  inches tall.
