Question

A cube has a surface area of 3,750 square feet. Find the length of one side.

Answer 1

Surface area of a cube = $6a^2$

So 3,750 = $6a^2$

We need to find the value for $"a^2"$

Eliminate 6 from both sides using division

$3750/6 = 6a^2/6 625 = a^2$

Now we have the area of one side of the square since the area of a square equal $a^2$

Square root $25$ and you get one side of the square.

$\sqrt{625}$ =
