Since two people take both courses, we can subtract two from 7, 8, and 21, giving us 5, 6, and 19.
Add 5 and 6 together to get 11. Since eleven students are in those two groups, we can answer this. The answer will be 11/19.
1-39 ODD:
1,3,5,7,9,11,13,15,17,19,21,23,25,27,29,31,33,35,37,39
Now you'd add them all up.
1+3+5+7+9 = 25
11+13+15+17+19 = 75
21+23+25+27+29 = 125
31+33+35+37+39 = 175
Add the totals:
25+75+125+175
The answer would be 400.

Answer:
225 cm ^ 3
Step-by-step explanation:
First find the volume of the rectangle that is most horizontal.
L * W * H = 10 * 3 * 3 = 90
Then find the volume of the most vertical rectangle
L * W * H = 15 * 3 * 3 = 135
add them together to get...
225
