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.
