Response

Given a rectangular sheet of cardboard 15in by 25in. If a small square of the same size is cut from each corner and each side folded up along the cuts to form a lidless box.

What is the volume of the box?

What size(s) of the square would produce a box of Volume equal to 400 cubic inches?

Prepare demonstrations/ solutions to this problem using
a. Algebra Xpresser
b. GSP
c. Spreadsheets
