I disagree with marks answer
The crust can be chosen in C(3,1) ways or 3 ways
the cheese can be chosen in C(3,1) or 3 ways if you want only one cheese
But the 3 toppings can be chosen in C(7,3) or 35 ways
So the number of possible pizzas with 3 toppings and 1 cheese with 3 different crusts
= 3x35x3 = 315 ways
