Answer 1

Answer:

$SA=672\ yd^2$

The net in the attached figure

Step-by-step explanation:

we know that

The surface area of the square pyramid using a net, is equal to the area of a square plus the area of its four lateral triangular faces

so

$SA=16^2+4[\frac{1}{2}(16)(13)]$

$SA=256+416=672\ yd^2$
