So the 2-inch squares you cut from each corner, and the FOLDED UP -- these make the height of the box.
Volume = Length * Width * Height
Our volume is 8450, our height is 2
8450 = Length * Width * 2
Since the box has a square base, the length and the width are the same, so we will replace the width with Length
8450 = Length * Length * 2
Divide both sides by 2
4225 = Length2
Take the square root of both sides to find the length
65 = Length = Width because it has a square base.
So the dimensions are
65 in. by 65 in.
