2(10 * 4 + 10 * 7 + 4 * 7) is surface area.
10 + 4 + 7 is neither.
2 * 7 * 4 + 2 * 10 * 7 + 2 * 4 * 10 is neither.

Let's say Alice is 4 feet tall and Bob is 6 feet tall. The ratio of their heights is the required Alice:Bob = 2:3. That means Bob is 3/2 = 1.5 times taller than Alice.
15%=3
5%=1
5(20)=100
1(20)=20
So, there are 20 students in the class.
