Question 385993
What is the volume of a cube with a surface area of 48ft^2?  
.
A cube has six sides -- and, being a "cube" length of all sides are equal thus:
Let x = length of one side
then
{{{6(x^2) = 48}}}
{{{x^2 = 8}}}
{{{x = sqrt(8)}}}
{{{x = 2*sqrt(2)}}}
.
volume of cube:
x^3 = (2*sqrt(2))^3 = 22.63 cubic ft
