Question

What is the surface area of the square pyramid? (100 POINTS BTW) (:
A:60 cm2

B:132 cm2

C:228 cm2

D:288 cm2

Answer 1

Step-by-step explanation:

A square pyramid has 5 faces.

Surface area of the base which is a square= 6×6 cm²

= 36cm²

There are 4 triangles.

Area of one right angle triangle =

$\frac{1}{2} \times 6 \times 8$

$= 3 \times 8$

=24 cm²

Area of the 4 triangles = 24×4cm ²

= 96cm²

Surface area of the square pyramid= 36+96cm²

= 132cm²
