a rectangular solid is dilated by a factor of 0.5.

how many times larger is the volume of the resulting solid than the volume of the original solid?

The answer to this question:

If you are looking for the volume of the object. To find the volume of a rectangle. You do L*W*H.

So if one side of the rectangle is 0.5. And they do not give the other sizes of the rectangle. I would assume that all sides are the same. So just do 0.5*0.5*0.5 to get 0.125
