Question

A swimming pool is 8 meters long. 6 meters wide, and 2 meters deep. The water-resistant paint needed for the pool costs $6 per square meter. How much will it cost to paint? How much paint do you need to paint the pool? ​

A) how many faces of the pool do you have to paint?
B) How much paint (in square meter) do you need to paint the pool?
C) How much will it cost to paint the pool

Answer 1

Explanation:

A) You are painting 5 faces, four sides and the bottom, of the pool because you are not painting the top of the pool.

B) You need 104 square meters to paint the pool.

Assuming the pool is a rectangular prism, use the surface area equation:

SA = wl + 2(hl) + 2(hw)

Note: Do not include times 2 for wl because we are only including the bottom of the pool.

l = 8 meters

w = 6 meters

h = 2 meters

SA = (6)(8) + 2((2)(8)) + 2((2)(6))

SA = 104 square meters

C) The paint with cost $624 total. $104 times 6 square meters equals $624
