Intro to probability

A certain pizza restaurant offers three different sizes of pizza and eight different toppings.
How many distinct pizzas having two different toppings can be made?
======================================

I think part of the answer to the question is
(8)\
(2)/ where I choose 2 toppings from 8.

==> 8!/ (6!* 2!)= 28

But im not sure what to do from there, if it's correct.

    ok so far.

    Wouldn't those 28 ways also be available in each of the 3 sizes of pizza?

    so final number of ways = 3x28 = 84
