a rectanglar prism has a volume of 48 cubic feet and a surface area of ** square feet. What are its dimensions?

I assume that ** = 88
l * w = 48, so l = 48/w
2l + 2w = 88
Substitute 48/w for l in second equation and solve for w. Insert that value into the first equation and solve for l. Check by inserting both values into the second equation.
