Answer to Question #124937 in Geometry for Jonathan

Question

If the volume for 3-D polyhedra A is 200 cm3 and the volume for 3-D polyhedral B is 800 cm3, how many times bigger is the volume of pyramid B than pyramid A?

0.4%
4%
40%
400%

Answer 1

The correct answer is 400%. We get this by comparing the volumes of 3-D polyhedral B to that of 3-D polyhedral A and convert to percentage. That is to say percentage change = (volume of B/volume of A) x 100%

=(800/200) x 100%

=4 x 100%

=400%

Therefore, the volume of pyramid B is 400% bigger than that of pyramid A.
