Question

A given cube has a volume of 1728 cubic inches. Find the length of an edge, area of one side, surface area, and surface area in square feet.

Answer 1

for a cube
v=s³
SA=6s²
area of 1 side=s²
s=length of 1 edge

so

1728=s³
cube root both sides
12=s

length of an edge is 12in

the area of one side is 12² or 144 in²

surface area is 6s² or 6(144) or 864 in²
