Zoe wanted to create a square based pyramid for her project. She needs to cover the entire pyramid with wrapping paper. Based on the model below, what is the minimum amount of paper she will need

161 in^2

i am so sorry if I got this wrong..

38.5

step-by-step explanation:

lets say, first number = r

second number = 3r+7

total = 49

(r)+(3r+7)= 49

4r+7 = 49

4r = 42

r = 42/4

r= 10.5

3r+7 = 3(10.5)+7 = 38.5

hope this

7

step-by-step explanation:

the answer would be 7
