Answer:
The wood from the birch tree has a greater density than the wood that came from the cypress tree.
Step-by-step explanation:
Density formula: mass/volume
2 times 4 times 3=24 meters for the volume
Birch tree: 16/24 is the density
3 times 5 times 2=30 meters for the volume
Cypress tree: 15.3/30 is the density
If we convert the densities of each piece of wood to decimal it will be easier to determine which has a greater density.
So birch tree: 0.6 repeating is the density
Cypress tree: 0.51 is the density
Therefore the wood that came from the birch tree has a greater density than the wood that came from the cypress tree.

Answer:
1,458,783,255,601
Step-by-step explanation:
(-1,099)^2
Break it apart:
(-1,099)*(-1,099)
Multiply the signs and numbers:
Two negatives make a positive so you are left with just 1,207,801.
Next, you square 1,207,801:
(1,207,801)*(1,207,801)
And you get the number 1,458,783,255,601
A rotation on its axis of 180 degrees
