Answer:
Total surface area of the pyramid is 236.16cm² and the expression is
2bs + s²
Step-by-step explanation:
Total surface area of a square pyramid is expressed as;
TSA = 2bs + Base Area
b is the side length of the base = 8.2cm
s is the slant height of the triangular side = 10.3cm
Base area = s²
Base area = 8.2²
Base area = 67.24cm²
TSA = 2(8.2)(10.3)+67.24
TSA = 168.92+67.24
TSA = 236.16cm²
Hence the total surface area of the pyramid is 236.16cm² and the expression is 2bs + s²
