Riley’s family is putting a rectangular pool in his backyard. the dimensions of the pool will be 12 ft. by 24 ft. by 5 ft.

the contractor building the pool needs to know how much lining he needs before starting to pour the concrete. how many square feet of liner will he need? (hint: the liner will need to cover all the inside concrete surfaces of the pool, but not the top of the pool.)

936 or 648

Step-by-step explanation:

I'm late by like 3 years but if you do the square's surface area, it would be 12*24=288*2=576

24*5=120*2=240

12*5= 60*2=120

Then add,

576+240+120=936, but again what the person said its a pool, so you wouldn't really include the top bit in a pool because a pool has no lid to the top, so you could just do 936-288=648

32
