Sam is ordering an ice cream dessert. He must order a size, a flavor of ice cream, and a topping. There are 2 sizes, 3 flavors, and 2 toppings to choose from. How many different ice cream desserts could he order?

Sam can order 12 ice cream deserts.

Step-by-step explanation:

Sam has choices from 2 sizes, 3 flavors, and 2 toppings.

For 2 sizes come 3 flavors, this means there are 2 * 3 = 6 types of ice creams Sam can get from the combination of sizes and flavors.

Now these 6 combinations come with additional choice of 2 toppings. This means when these the toppings are added, Sam gets 6*2 = 12 different types of ice creams Sam can by.

Thus, Sam can order 12 different ice-creams.
