3 ptA company wants to find the cheapest way to box its products. The latest product they have designed needs 30 cubic units of space. Give the dimensions of the box that requires the least amount of packaging material (surface area) First find all the ways to make a prism with 30 cubes. There are 4 ways. Hint: make a chart.

3 ptThe following boxes all have a volume of 30 cubic units. Notice all the dimensions are FACTORS of 30.

1 x 1 x 301 x 2 x 151 x 3 x 101 x 5 x 62 x 3 x 5

The 2 x 3 x 5 box requires the least amount of packaging material because it is the shape that looks most like a cube.
