You would need 6 quarts of milk. You would do 24(2) then you take 48 and divide it by 288 and you get 6.
2.7/6=x/18
2.7 x 18 = 6x
48.6 = 6x
8.1= x

If the legs are length a and b and hyptonuse is c then
a²+b²=c²
so
if the legs are 20 and 21 and the hypotnuse is x then
20²+21²=x²
400+441=x²
841=x²
29=x
