Answer:
The surface area 76.32 in^2
Step-by-step explanation:
To find the surface area of a square pyramid we have to find the area of the base and the area of the sides and add them together.
Area of the base:
Since the base is a square, all we have to do is multiply 3.6 by 3.6.
3.6 * 3.6 = 12.96
The area of the base is 12.96 in^2
Area of the sides:
Since the sides are triangles, to find the area we have to multiply the length by the height and divide by 2.
3.6 * 8.8 = 31.68
31.68/2 = 15.84
The area of one of the sides is 15.84
Surface Area:
To find the surface area we have to add the area of the base and the area of the 4 sides together.
12.96 + 4(15.84)
12.96 + 63.36 = 76.32
The surface area is 76.32 in^2
