pyramid B than pyramid A?
15
32
54
75

Hello! Your answer is D: 75.

Step-by-step explanation:

First we need to find the volume of pyramid A in order to solve this problem:

The formula for the pyramid is: V=(B)(h)

Now we plug in the numbers:

V=(81)(4)

V=(324)

V=108in³

Now we divide pyramid B's volume by pyramid A's:

8,100/108 = 75

So the volume pyramid B is 75 times bigger than the volume of pyramid A!

Hope this helps!
