Very easy, William! Since "tripled" merely means "multiply it by three", do exactly that to each dimension. Follow-up question: what happens to area if you do that?
Mark M.
If all dimensions are multiplied by 3 then the volume is multiplied by 27.
If all dimensions are multiplied by 3 then the surface area is multiplied by 9.
