Answer:
[tex]336 m^2[/tex]
Step-by-step explanation:
The surface area of a square pyramid is the sum of the area of the squared base + 4 times the area of each triangular face, therefore:
[tex]A=A_b + 4A_t[/tex]
where:
[tex]A_b=L^2[/tex] is the area of the base, where
L is the length of the base
[tex]A_t=\frac{1}{2}Lh[/tex] is the area of each triangular face, where
h is the height of the face
Substituting,
[tex]A=L^2+2Lh[/tex]
For the model in this problem,
L = 12
h = 8
Therefore, the surface area here is:
[tex]A=12^2 +2(12)(8)=336[/tex]
