Blog Assignment #6 -- ABC Toy Company




Blog Assignment #6 is due April 30th!

ABC Toy Company is planning to market a set of children’s blocks. The package of blocks will contain 26 letter blocks, 10 number blocks, and 12 animal blocks for a total of 48 blocks in the package. Each block is a cube with 1-inch edges, so each block has a volume of 1 cubic inch.

The company wants to arrange the 48 blocks in the shape of a rectangular prism and then package them into a box that exactly fits the prism.

1. Find ALL the ways 48 cubes can be arranged into a rectangular prism.
a. How many ways are there to arrange the 48 cubes?
b. What are the dimensions (length, width, and height) of each rectangular prism?


2. Of the rectangular prisms you found, which one gives the least surface area?
a. Give the dimensions of this prism.
b. What is the surface area of this rectangular prism?


3. Explain why the ABC Toy Company needs to package the blocks using the rectangular prism that gives the smallest surface area.
