Answer:
Surface area of a square pyramid is:
112 cm²
Step-by-step explanation:
The surface area of square pyramid is given by:
S=2bs+b²
Where b is the length of base and s is the slant height.
and Area of base=b²
Here, s=12 cm
and Area of base=b²=16 cm²
⇒ b=4 cm
Hence, Surface Area=2×12×4+4×4
= 112 cm²
Hence, surface area of a square pyramid is:
112 cm²
