Question

A cube has a volume of 512 cm3.

Answer 1

Volume of cube is side power 3
therfore cubic root volume = side length
volume = 512 --> cubic root 512 =8 cm
side length is 8 cm if it was doubled
side length= 16 cm
therefore side length after doubling =
side power 3
(16) to the power 3 = 4096 cm3
