Hello!
I don't exactly understand your question. If you mean to be asking whether or not 1002 is geater than 100, it is.
If you mean to be asking to add it: 102 + 900 + 100 = 1102
Assuming that the cube has equal dimensions, it would be:
8 x 8 x 8 = 512 ft^3
5 divided by one half, would be 2.5, since its half of 5.
Answer:
the answer is multiple ............
15%=3
5%=1
5(20)=100
1(20)=20
So, there are 20 students in the class.
