Answer:
220.8 in.²
Step-by-step explanation:
Area of the pyramid = area of the square + 4(area of the triangle)
Area of square = s²
s = 9.2 in.
Area of the square = 9.2² = 84.64 cm²
✔️Area of the 4 triangles = 4(½*bh)
b = 9.2 in.
h = 7.4 in.
Area = 4(½*9.2*7.4) = 136.16 in²
✅Surface area = 84.64 + 136.16 = 220.8 in.²
