Answer:
5 L
Step-by-step explanation:
As given in question,
1 L can fill 4.2 cups.
So, 1 cup can hold 
L of fluid.
Therefore,
21 cups can hold = × 21
= 5 L
So, there is 5 L of fluid in 21 cups.
Answer:
m = 686.
Step-by-step explanation:
Direct variation :
m= kl^3 where k is a constant.
m = 250 when l = 5, so
250 = k *(5)^3
k = 250 / 125 = 2
So the equation of variation is m = 2l^3.
When l = 7:
m = 2 * (7)*3
= 2 * 343
= 686.
