10 qt = how many cups

1 quart = 4 cups

10 * 4 = 40

So 10 quarts is 40 cups.

Every quart has two pints 1 Q = 2 P

Every pint has two cups 1 P = 2 C

Two pints have two cups 2 P = 4 C

Which mean that one quart has four pints 1 Q = 4 C

So then just multiply the four cups times 10 quarts, and you'll get 40 cups
