Answer:
SA = 126 square cm
Step-by-step explanation:
SA = 2(l · w) + 2(h · w) + 2(l · h)
SA = 2(5 · 6) + 2(6 · 3) + 2(5 · 3)
SA = 60 + 36 + 30
SA = 126 sq cm
Answer: that is not a question
Step-by-step explanation:
Using the Fundamental Counting Theorem, there are 60 different ways to order the pizza.
<h3>What is the Fundamental Counting Theorem?</h3>
It is a theorem that states that if there are n things, each with
ways to be done, each thing independent of the other, the number of ways they can be done is:

For this problem, the parameters are found as follows:
- For the sauce, there are 2 options, cheese or tomato, hence
.
- For the topping, there are 4 options, but the options may be combined, for example, Pepperoni and Sausage, hence
.
- The topping can be added to either all the pizza or only half the pizza, hence
.
Thus the number of ways is given by:
N = 2 x 15 x 2 = 60.
