A. 15 inches

B. 15 square inches

C. 216 inches

D. 216 square inches

E. 260 inches

H = 15 inches

Step-by-step explanation:

You know the volume is: V = L * W * H

You know the length and the width, therefore

18 * 12 * H = 3240

216H = 3240

H = 3240/216

H = 15 inches is the height of the tank

You can make sure it is right:

18 * 12 * 15 = 3240
