Asmall leak is causing a swimming pool to lose 1/2 gallon of water per hour. what is the change in the amount of water in 4 hours?

answer:

e

step-by-step explanation:

The answer is B) 1/3.

A rectangular prism has 6 faces.  The area of each is given by length * width.

The area of the top and bottom is given by 25(4) = 100 sq. in.
The area of the front and back is given by 25(8) = 200 sq. in.
The area of the right and left is given by 4(8) = 32.

There are only 2 faces that have an area that is not a multiple of 100; 2/6 = 1/3.
