Question

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

Answer 1

Answer: 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
