Homework Help: Math

Posted by Cadmus on Friday, January 11, 2013 at 2:29pm.

An open-topped box can be created by cutting congruent squares from each of the four corners of a piece of cardboard that has dimensions of 20cm by 30cm and folding up the sides. Determine the dimensions of the squares that must be cut to create a box with a volume of 1008cm^3.
length=30-2x
width=20-2x
h=x
I don't get this because x and cm aren't interchangeable digits.
