It would be called an ecological model.
Answer:
1? Because its the only number beetween 2 and 0.
Use similar volume to calculate
which is the (ratio of edges)^3 = (ration of volume)
so just put the numbers in, let the volume of smaller pyramid be y.
(3/4)^3 = y/320
27/64 = y/320
y=135in3

y-intercept:8</span>
Cos x=5/12. Solve for x which is 65.37 degrees.
