The inside of a rectangular swimming pool is going to be painted. The pool is 8 feet wide, 25 feet long, and 5 feet deep. What is the surface area of the five faces to be painted?

total area = 530 ft^2

Step-by-step explanation:

bottom = 8 x 25 = 200 ft^2

2 sides = 8 x 5 x 2 = 80 ft^2

2 other sides = 25 x 5 x 2 = 250 ft^2

200 + 80 + 250 = 530 ft ^2

it is a. 4.2 because 7.6-3.4 gets the remaining length of 4.2. i might be wrong but i am pretty sure this is the answer.
