Rosa has 16 unit cubes. How many different rectangular prisms can she build with the cubes?
Since the rectangular prism is formed by the unit cubes, each dimension of the prism must be a whole number of cubes.
Given that Rosa has
To find these combinations, look at the factors of
Pick any two of these factors and determine if there is a third value from this list so that the product of the three factors is
Hence, Rosa can build 4 different rectangular prisms with 16 unit cubes.
