Question

A swimming pool is 8 m long, 6 m wide and 1.5 m deep. The water resistant paint needed for the pool costs $6 per square meter. How much will it cost to paint the interior surfaces of the pool? How many liters of water will be needed to fill it?

Answer 1

Should be like this:
one side S=a*b=6*1,5=9
9*2=18
other side S=8*1,5=12
12*2=24
the base S=8*1,5=12
it can fit 6*8*1,5=72 liters
