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? A. 0.4% B. 4% C. 40% D. 400%

Answer 1

You can use the volume of pyramid B divided by volume of pyramid A and multiply 100%. That is 800/200*100%=400%. So the answer is D. 400%.

Answer 2

Answer:

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.

⇒$\frac{\text{Volume of Polyhedral B}}{\text{Volume of Polyhedral A}} \times 100$

⇒$\frac{800}{200} \times 100$

⇒$4 \times 100$

⇒$400\%$

Thus Option D is correct.

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