Answer:
The surface area of the square pyramid is [tex]144\ m^{2}[/tex]
Step-by-step explanation:
we know that
The surface area of the square pyramid is equal to
[tex]SA=B+Ph/2[/tex]
where
B is the area of the base
P is the perimeter of the base
h is the height of the pyramid
Find the area of the base B
[tex]B=6^{2}=36\ m^{2}[/tex]
Find the perimeter of the base P
[tex]P=4*6=24\ m[/tex]
The height is [tex]h=9\ m[/tex]
substitute the values
[tex]SA=36+24*9/2=144\ m^{2}[/tex]
Answer:
yeah its 144
