Math Question?

rise in water height = 2 cu ft / base area = 2 cu ft/(2 ft x 2 ft) = 0.5 ft = 6 inches

V1 = 10 = 2 * 2 * h1
V2 = 10 + 2 = 2 * 2 * h2

10 = 4 * h1
2.5 = h1

12 = 4 * h2
3 = h2

h2 - h1 = 3 - 2.5 = 0.5

0.5 feet = 6 inches

A tank that has a height of 8 feet
and a base that is 2 feet by 2 feet contains 10 cubic feet of water.
If 2 cubic feet of water are added to the tank
how many inches will the water in the tank rise?
Water in the tank will rise by 24 inches.

hint, 1 gallon is 231 cubic inches
