Question 319493: The larger of two similar pyramids has 8 times the volume of the smaller. If the smaller pyramid is 5 inches high, how high is the larger pyramid?

for similar figures , the ratio of the volumes is the cube of the ratio of the sides (or height)
the cube root of 8 is 2 , so the larger pyramid is twice as high as the smaller one
