Question

The volume of a rectangular prism is 125cm3. If the width of the prism is multiplied by a scale factor of 2, what is the volume of the new prism

Answer 1

The volume of a rectangular prism is given by

$V\text{ = L X W X H}$

Since V = 125 cm3

Therefore 125 = LWH

When the width is multiplied by 2, the new dimensions will be

V = L X 2W X H

V = 2LWH

Then, if we compare this with the initial dimension

$\text{LWH =}\frac{125}{2}cm^3$
