Question

if the height of a rectangular prism is decreased by a scale factor of 1/2 how will the volume of the prism change????????​

Answer 1

Decrease by half.

Explanation:

Let's say the length, width, and height is x,y,z respectively.

V = xyz

Now, when z is decreased by half, we get xyz : 2 which can either be written as (xyz) : 2 or xy(z:2)

So in short, if the height decrease by half, the volume will decrease in half.
