Question

Each dimension of a rectangular prism is increased by 30%. What percent of the original volume is the volume of the new prism?

Answer 1

say the original prism is: 1*1*1
The volume of this prism is 1 cubic unit.
increasing all of this by 30% makes: 1.3*1.3*1.3
The volume of this prism is 2.197 cubic units.
It's nice to start out with an original volume of 1, since it's easy to tell that 2.197 is a 219.7% increase in volume.

Answer 2

Thank you, that helped (:
