Question

In constructing a graph that compares average water usage per household in different communities, you choose to use cubes of different sizes. If the cubes are drawn so that their volumes are proportional to the volumes of water usage in different comunities, is the resulting graph misleading? Why or why not?

Answer 1

Since volume of similar objects is proportional to the cube of their sides, your cubes will probably be too large

e.g.
suppose we have cubes of sides 1, 2, 3, 4, 5, ..
their corresponding volumes are:
1, 8, 27, 64, 125, ...

Answer 2

If the cubes are proportional, then it isn't misleading.
