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? a. 0.4% b. 4% c. 40% d. 400%

400%

Step-by-step explanation:

Given :

The volume for 3-D polyhedral A is 200 cubic cm.

The volume for 3-D polyhedral B is 800 cubic cm.

To Find: how many times bigger is the volume of pyramid B than pyramid A?

Solution:

Since we are supposed to find how many times bigger is the volume of pyramid B than pyramid A.

⇒

⇒

⇒

⇒

Thus Option D is correct.

Hence the volume of pyramid B is 400% times bigger than pyramid A.
