How do you solve the problem Nu is disigning a rectangular sandbox The bottom is 16 square feet which dimensions requie the least amount of material for the sides of the sandbox?

Ok, an important part of this is that shapes can be categorized into multiple groups.

It goes something like this in this case: Quadrilateral

V

Rectangle

V

Square

When dealing with shapes, regular polygons always have less perimeter than irregular for the same area. Here, a square would have a perimeter of 16, with 4x4 dimensions; the next closest rectangle would have a perimeter of 20, with dimensions of 8x2; the last rectangle you could make would have a perimeter of 34, with dimensions of 16x1.
