3. ahhh, now you changed the wording.

Let the width of rectangle be x
then its length is 2x
Volume of rectangular prism = (2x^2)(h)

Volume of triangular prism = Area of base(h)
area of base = Volume of triangular prism/h
= Volume of triangular prism/(Volume of rectangular prism/2x^2)
= 2x^2(Volume of triangular prism)/(Volume of rectangular prism

Do the two prisms have the same volume ?
