Volume of Pyramids — Quiz

Question 7 • Grade 7 Mathematics

Each of the dimensions of a pyramid are doubled. What is true about the volume of the new pyramid?

Answer
A
The new pyramid has a volume that is 2 times the volume of the original pyramid.
B
The new pyramid has a volume that is 4 times the volume of the original pyramid.
C
The new pyramid has a volume that is 1 half the volume of the original pyramid.
D
The new pyramid has a volume that is 8 times the volume of the original pyramid.

Explanation

A pyramid’s volume depends on its base area and height: V = (1/3)Bh. Doubling every dimension makes the base area 4 times as large and the height 2 times as large, so the volume becomes 4 × 2 = 8 times the original. Therefore, the new pyramid has a volume that is 8 times the original volume.
