Answer:
The volume of pyramid B is 3.5 times greater than the volume of pyramid A
Step-by-step explanation:
The area of squared based a pyramid is given by:
![Area = \frac{1}{3}*s*s*h](https://tex.z-dn.net/?f=Area%20%3D%20%5Cfrac%7B1%7D%7B3%7D%2As%2As%2Ah)
Where 's' the length of the side of the base and 'h' is the height.
For pyramid A:
h= 100 m
s= 356/4 = 89 m
![Area_A = \frac{1}{3}*89*89*100\\Area_A=264,033.33\ m^3](https://tex.z-dn.net/?f=Area_A%20%3D%20%5Cfrac%7B1%7D%7B3%7D%2A89%2A89%2A100%5C%5CArea_A%3D264%2C033.33%5C%20m%5E3)
For pyramid B:
h= 215 m
s= 456/4 = 114 m
![Area_B = \frac{1}{3}*114*114*215\\Area_B=931,380\ m^3](https://tex.z-dn.net/?f=Area_B%20%3D%20%5Cfrac%7B1%7D%7B3%7D%2A114%2A114%2A215%5C%5CArea_B%3D931%2C380%5C%20m%5E3)
Pyramid B has a greater volume and the ratio between volumes is:
![\frac{Area_B}{Area_A} =\frac{931,380}{264,033.33}\\\frac{Area_B}{Area_A} =3.5](https://tex.z-dn.net/?f=%5Cfrac%7BArea_B%7D%7BArea_A%7D%20%3D%5Cfrac%7B931%2C380%7D%7B264%2C033.33%7D%5C%5C%5Cfrac%7BArea_B%7D%7BArea_A%7D%20%3D3.5)
Answer:
That is true!
![1,200 * 11 = 13,200](https://tex.z-dn.net/?f=1%2C200%20%2A%2011%20%3D%2013%2C200)
Let me know if you need more help with multiplication. I may be able to help.
Have a great day.
