Okay, firstly, let's list some multiples of 5 and 8.
5 : 5, 10, 15, 20, 35, 30, 35, 40, 45, 50, 55, 60, 65, 70, 75, 80, 85, 90
8 : 8, 16, 24, 32, 40, 48, 56, 64, 72, 80, 88, 96, 104, 112, 120
I've emboldened two of the multiples of 5 and 8 that are the exact same in both lists. They are 40 and 80. And the lesser multiple out of the two of them is 40. So we'll be using the number 40 to simplify
.
So let's divide, the numerator before the denominator. 120 ÷ 40 is 3. And 160 ÷ 40 = 4. Simplified, using the numbers we just found, our final answer is

Answer: 27 times bigger.
Step-by-step explanation:
You need to use the following formula to find the volume of a Square pyramid:
Where "s" is the edge of a side of the square base and "h" is the height of the pyramid.
Knowing that:
You can find the volume of the Pyramid A and the volume of the Pyramid B:
Finally divide the volume of the Pyramid B and the volume of the Pyramid A, in order to find how many times bigger than the Pyramid A is the Pyramid B.
You get:
