Find NOK
From the attached triangle, we have:
--- Corresponding angles
And
Substitute for LOK and LON
Make NOK the subject
As you can see, 4 of the 24 students don't partecipate in any activity. This clearly implies a ratio of 4:24, or 1:6.
We could infer that this ratio holds for the whole school, or even for all the boys and girls of that age.
That's the point of surveys and inferring: you gather data about a relatively small group, and then assume that the proportions you have are valid for a much larger group.
That's why it is important that the group that you survey is balanced and unbiased.
We don't know what the dimensions are, but any numbers that have a sum of 120 will work. Let's use 3, 4, and 10.
3 x 4 = 12 10 x 12 = 120
But if you double each dimension:
6 x 8 = 48 48 x 20 = 960 To find how much the sums changed:
960 / 120 = 8
The new volume is 8 times what it originally was! 960 in.
