the base of a rectangular prism is congruent to the base of a pyramid. The height of the pyramid is 3 times the height of the prism. Which figure has a greater volume? Explain.
I'm terrible with these kind of word problems. If you could explain that would be great.

can someone please help me!?!

ht. of rectangle = h.
ht. of pyramid = 3h.
Vr = Ab*h = Volume of rectangle.
Vp = Ab*3h/3,
The "3s" cancel.
Therefore, Vp = Vr = Ab*h.
Based on the dimensions given,the
volume of the rectangle is equal to
the volume of the pyramid.
Ab*h = Volume of pyramid 
A rectangular prism has a base of 12cm2 and a height of 6 cm what is its volume
