If you could explain to me how you get the answer, that will be great!

156

let me know if this is wrong

Step-by-step explanation:

first, find the surface area of the square base

6(6)=36

after that, find the surface area of the 4 triangular lateral faces

formula: SA=4(bh÷2)

then substitute

SA=4(6 x 10 ÷ 2)

solve

SA=4(30)

SA=120

add the surface area of the square base and the lateral faces

120+36=156

1 and 2

step-by-step explanation:

answer: 1,380

step-by-step explanation:

1: you turn %15 into a decimal by moving the decimal point two places to the left.

2: and then you multiply .15 by 1,200 , which will get you 180.00

3: from there you will add 180 to 1,200

4: which will get you 1,380

hope it *im kind of slow so idk if my answer is right*
