Question

if the volume for 3d pyramid a is 400cm3 and the volume for 3d pyramid b is 800cm3 ,how many time bigger is the volume of pyramid b than pyramid a

Answer 1

Answer:

2 times.

Step-by-step explanation:

We have been given that the volume for 3d pyramid a is $400\text{ cm}^3$ and the volume for 3d pyramid b is $800\text{ cm}^3$.

To find the volume of b is how many times greater than volume of pyramid a we will use proportions.

$\frac{\text{Volume of pyramid b}}{\text{Volume of pyramid a}}=\frac{800\text{ cm}^3}{400\text{cm}^3}$

$\frac{\text{Volume of pyramid b}}{\text{Volume of pyramid a}}=2$

$\frac{\text{Volume of pyramid b}}{\text{Volume of pyramid a}}*\text{Volume of pyramid a}=2*\text{Volume of pyramid a}$

$\text{Volume of pyramid b}=2*\text{Volume of pyramid b}$

Therefore, the volume of pyramid b is 2 times the volume of pyramid a.

Answer 2

It would just be Pyramid B divided by Pyramid A which is 800/400 which is 2.
