Answer:
75 times
Step-by-step explanation:
To calculate this we need to:
First, find the volume of Pyramid A:
The formula for the volume of a square pyramid is
V = (1/3)bh
Where;
Base area (b) = side^2 = 9^2 = 81 in^2
Volume (V) = (1/3)bh = (1/3)(81)(4) = 108 in^3
Now, we know the volume of Pyramid B is 8,100 in^3. To find out how many times bigger it is than Pyramid A, we can simply divide the volume of Pyramid B by the volume of Pyramid A:
Pyramid A → 108 in^3
Pyramid B → 8,100 in^3
8,100 in^3 ÷ 108 in^3 = 75
So, the volume of Pyramid B is 75 times bigger than the volume of Pyramid A.
