When multiplying by 4, you can simply multiply it by 2 twice (prime factorization).
In this example-
4 times 8 = 32
2 times 2 times 8 = 32

Because 3c is given cookies and 36 minus baked cookies can give value of total cookies
We need to find the surface area of the box. For this, we will do 2(L×W) + 2(L×H) + 2(H×W); Since each has a corresponding side, we multiply it by 2.
Let's find it with plugging it in.
2(2×1) + 2(2×1) + 2(1×1)
4+4+2=10
Now the surface area is 10 ft², let's just multiply .8 by that to find the price.
.8×10= 8
It'll cost $8 for Joseph to cover the box with wrapping paper.
