What is the surface area of the square pyramid?

enter your answer in the box.

240 inches squared.

Step-by-step explanation:

To find the surface area, find the area of each triangle and the square. Then add all the areas together.

Triangle - A = 1/2bh where b = 8 and h = 11. So the area of 1 triangle is A = 1/2*8*11 = 44. Since there are 4 triangles then 4*44 = 176 inches squared.

Square - A = s^2 where s = 8. So the area of the square is A = 2^2 = 8^2 = 64.

So all the areas add together to 176 + 64 = 240.

do you mean add both of the equations together

because if you do the answer is 10x-5

step-by-step explanation:

4x and 6y

im not sure though
