1 How much will it cost to paint the interior surfaces of the pool?

2 How many liters of water will be needed to fill it?

Answer 1

1.It means we need the surface area of the pool.so draw the pool and you will realize that its surface area is (8*1.5+8*1.5+6*1.5+6*1.5+8*6).That is 144.

Answer 2

2.You have to find the volume so 8*6*1.5=72 m^3

Answer 3

then convert to liters

Answer 4
