Question

If all of the sides of a prism are multiplied by 5, by what factor does the volume increase?

Answer 1

If one dimension of a 3-dimensional shape is doubled, the volume increases by 21 = 2.  If two dimensions of a 3-dimensional shape are doubled, the volume increases by 22 = 4.  If all three dimensions of a 3-D shape are doubled, the volume increases by 23 = 8.
