Answer:
160 units squared
Explanation:
First we need to find the surface area of one of the triangles;
(8*6*0.5)
24
Next, we find the surface area of all of the triangles;
(24*4)
96
The next step is to find the surface area of the square;
(8*8)
64
The last step is to fins the surface area of the whole thing.
(96+64)
160
The surface area of the pyramid is going to be 160 units squared
