Terrance needs to find the lateral surface area of the box shown below , assuming that the base is the bottom of the prism , which of the expressions below will give him the correct layers surface area? a. (14.5)(8.6)
b. (14.5 + 7)(8.6)
c. (14.5 + 14.5 + 7 + 7)(8.6)
d. (14.5 + 14.5 + 7 + 7)(8.6) +2(14.5)(7)

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24

time to try the rest on your own! if you put the answers below in a comment, i'll check them for you!
