First you multiply the two equations, equaling 3000000 kg and 60000 kg respectively. Once you have those numbers, you divide the Oakland mass by the Mapleville mass, so 3000000/60000. The answer is 50, to the tree is B, 50 times as big.
31/45

The side length of the square base is 18 inches and the height of the pyramid is 9 inches.
Step-by-step explanation:
Step 1:
The volume of a square pyramid is calculated by multiplying the square of the base edge with the height of the pyramid and
.
The volume of a square pyramid, ![V = a^{2} \frac{h}{3}.](https://tex.z-dn.net/?f=V%20%3D%20a%5E%7B2%7D%20%5Cfrac%7Bh%7D%7B3%7D.)
Step 2:
From the given diagram, the base edge is the length of the four base edges which is x inches in this pyramid. a = x inches.
The height of the pyramid is from the base to the top, h =
inches .
The volume of a square pyramid, ![V = 972.](https://tex.z-dn.net/?f=V%20%3D%20972.)
Substituting the known values, we get
![972 = (x)^{2} (\frac{x}{2}) (\frac{1}{3} ) = \frac{x^{3} }{6} .](https://tex.z-dn.net/?f=972%20%3D%20%28x%29%5E%7B2%7D%20%28%5Cfrac%7Bx%7D%7B2%7D%29%20%20%28%5Cfrac%7B1%7D%7B3%7D%20%29%20%3D%20%5Cfrac%7Bx%5E%7B3%7D%20%7D%7B6%7D%20.)
![x^{3} = 6(972) = 5,832. x = \sqrt[3]{5,832} = 18.](https://tex.z-dn.net/?f=x%5E%7B3%7D%20%3D%206%28972%29%20%3D%205%2C832.%20x%20%3D%20%5Csqrt%5B3%5D%7B5%2C832%7D%20%3D%2018.)
So x is 18 inches long.
The side length
inches.
The height of the pyramid
inches.
Answer: 13.75
<u>Put the numbers in order</u>
10, 10, 11, 12, 13, 14, 20, 20
<u>Add</u>
10+10+11+12+13+14+20+20=110
