Answer:
384 cm²
Step-by-step explanation:
Since it is a square pyramid, the total surface area of the pyramid is the area of its square base plus the area of its 4 triangular faces.

Area of a triangular face
= ½ ×12 ×10
= 60 cm²

Base area of pyramid
= 12 ×12
= 144 cm²
∴ Surface area of pyramid
= 4(60) +144
= 240 +144
= 384 cm²
The S in supplementary<span> can be used to form the 8 in 180. The C in </span>complementary <span>can be used to form the 9 in 90. If we know that a set of </span>angles<span> form one of these special relationships, we can determine the measure of the other </span>angle<span>. To determine the supplement, subtract the given </span>angle<span> from 180.</span>
