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

2 times.

Step-by-step explanation:

We have been given that the volume for 3d pyramid a is and the volume for 3d pyramid b is .

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

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

i believe it's a.

i'm not sure on this one, most likely correct.

whole number data type

step-by-step explanation:
