Answer:
64
Step-by-step explanation:
You know that:
there are four different sizes of pizza
two types of crust
and eight toppings
With a one-topping pizza, all you have to do is multiply 4 by 2 and then by 8
If it helps to branch it all out so you can visually see it, that would be a great idea
But in short, 4x2x8 is 64, so there are 64 combinations

Answer:
396 Square feet
Step-by-step explanation:
1.) First find the side closest to you. 6 x 12 = 72. Then double it to match the parallel side. 72 x 2 = 144
2. Find the side to the right and left, 7 x 6 = 42. Then double it to match the parallel side. 42 x 2 =84
3.) Find the top side and bottom side. 12 x 7 = 84. Then double it to match the parallel side. 84 x 2 = 168
4.) Find the total surface area. 144+84+168=
5.) The total surface area is 396 square feet
