Directions: Using the digits 1 through 9, each only once, fill in the boxes to create 2 rectangular prisms so the volume of one rectangle is double the volume of the other rectangle.
What does it mean for one quantity to be double another’s?
One possible answer is a rectangular prism with dimensions of 2 by 8 by 9 would have a volume of 144 cubic units which is double the volume of one with dimensions of 4 by 3 by 6 (72 cubic units).
Another possible way is an 8 by 6 by 1 (48 cubic units) is double one with dimensions of 2 by 3 by 4 (24 cubic units).
