A team is to design a cover a box to hold a jigsaw puzzle. The design will use 525 square cm. The cardboard is precut to 29 cm x 33 cm. The depth of the box (x) can vary to fit the needs of your cover design. How deep should the box be in order to allow the area of 525 cm for your design? I'm puzzled at how to set up this problem...please help me! Thanks!

dimensions cm2
To get the area of the bottom after the sides are
folded up, I subtract from each side.

Use the quadratic formula

and
