Question

Find the surface area if the pyramid

Answer 1

Answer:
`533 yd^(2)`

Explanation:

The surface area of the base is:

(20 x 17.3) / 2

= 346 / 2

= 173

The surface area of one of the three identical triangles is:

(20 x 12) / 2

= 240 / 2

= 120

So in total, your answer would be one base plus three of those identical triangles:

173 + (3 x 120)

=
`533 yd^(2)`
