Question

Find the surface area of the square pyramid below.

Answer 1

Answer:

728 m^2

Step-by-step explanation:

There are 5 faces of the square pyramid.

You have to calculate area of each face and add them to find surface area.

Bottom face is a square, so

area = 14^2 = 196 m^2

All the other faces are triangle with same area, so

4 × triangle area

4 × ((1/2)×14×19)

4 × 133

532 m^2

Now add those areas,

(196 + 532) m^2

728 m^2
