This pyramid has the same base as the prism, and its height is three times the height of the prism. What is the ratio of the volume of the pyramid to the volume of the prism?
okay let h be the height of prism
so ATQ, height of pyramid = 3h
put this in the formule
The volume of a pyramid = base x height x (1/3)
The volume of a prism = base x height
and find their ratio so simple
you will get the answer as 1
