The leg rule is hypotenuse/leg and the altitude rule is side 1/altitude=altitude/side 2
Proportions are very simple once you get the hang of them! What you do is cross multiple. :)
1. x/8=5/16
You first start by multiplying x and 16
Then multiply 5 and 8
So now you have 16x=40
Finally divide 16 from each side
You get: x+0.4!
2. 5/12=15/x
Remember to cross-multiply!
Now we have 5x=180
Next divide 5 from each side
You get: x=36!
Box A : 5 x 2 x 3 = 30 cubic cm
Box B: 2 x 2 x 6 = 24 cubic cm
Box C: 6 x 3 x 2 = 30 cubic cm
