Volume of Pyramids

Question 11 • Math 7 B (M12 25/26 S2)

Suppose a pyramid’s dimensions are tripled. What is the ratio of this new, larger pyramid’s volume to that of the original pyramid?

Answer
A
The new volume is one third the original volume.
B
The new volume is triple the original volume.
C
The new volume is 9 times the original volume.
D
The new volume is 27 times the original volume.

Explanation

A pyramid’s volume depends on three dimensions: length, width, and height. Tripling every dimension multiplies the volume by 3 × 3 × 3 = 27, so the new pyramid’s volume is 27 times the original volume.
