if you have 63 diffrent combinations how many diffrent combinations can you make with 1 crust , and 3 diffrent toppings , and 1 type of cheese ?

I don't know how the 63 fits in, but using all ingredients with "1 crust , and 3 diffrent toppings , and 1 type of cheese" there are only 3 combinations.
