Answer:
12 different ice cream desserts.
Step-by-step explanation:
To determine the number of different ice cream desserts Rafael could order, you can multiply the number of choices for each category:
Number of sizes = 3
Number of flavors = 1
Number of toppings = 4
Total number of different combinations = 3 (sizes) * 1 (flavor) * 4 (toppings) = 12
Therefore, Rafael could order 12 different ice cream desserts.
