Rectangular Prism

The equation for the volume of a rectangular prism is:

$Volume=width\times length\times height$

If we multiply the width by 2, the length by 3, and the height by 4 in this equation, we have to do the same to the other side so the equation remains true.

$2\times3\times4\times Volume=(2\times width)\times(3\times length)\times(4\times height)$

$24\times Volume=(2\times width)\times(3\times length)\times(4\times height)$

Therefore the volume will be 24 times it's original value.
