Answer:

72 square inches

Explanation:

The surface area is the sum of all the sides' areas.

**I am assuming the pyramid is a square pyramid based on observation.

There is one 4 by 4 square: area =

There are 4 congruent triangles with height 7 and base 4: area of a single triangle = 1/2 * b * h;
(7*4)/(2)=14

14 * 4 = 56

Add 56 and 16 = 72
