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
