Answer 9

but google does. simple search pulled this up,

you know, 12 inches make a foot.

thus, 6 inch = 0.5 foot.

assume the thickness of the wall to be 6 inches [same as of block], the volume of the wall= 7 x 20 x 0.5 = 70 cubic feet.

thus, the number of blocks needed = 10 x 70 = 700.

thus, the cost = $75 x 700 / 1000 = $52.5.
