Why Do Some Projects Fail Despite Best Efforts?

Homework Statement

An open box is required to have a volume of 10 m^3.
1) Express the amount, A, of material needed to make such a box as afunction of the length, x, of a side of the square base.

Relevant Equations

V=lbh
A=lb

I tried my best but I couldn't get anywhere...

You need to show some work. Translate the homework statement into equations that include the 10 m^3 and x. The equations should reflect the fact that the box has a square base.

The phrasing of the problem is a little unclear, but I am guessing that the amount of material should also include the amount on the sides (i.e. your second equation is incorrect).

Open box is a bit unclear but I guess it should have bottom but no lid
