PLEASE HELP.

THANK YOU.

Let Y = edge of a cube.

Y + 0.5Y = 1.5Y = new edge of the cube.

Then old volume is Y^3

New volume is (1.5Y)^3 = 2.375Y^3.

%increase = ([3.375Y^3 - Y^3]/Y^3) x 100 = x%. It looks like 237.5% to me but check it closely.

Try it with 1" cube changing to 1.5".

Or 2" cube changing to 3"

Or 3" cube changing to 4.5". I think all of those are 50% changes but check it out.
