Answer:

Explanation:

The slant height of one side of this pyramid is 5, and the base of this side is 4. Thus, the area of one slant side is (1/2)(5)(4) = 10 units^2.

There are 4 such sides. Thus, the total slant surface area is 4(10 units^2), or 40 units^2.

If you also want to include the base area, the total would be

40 units^2 + 16 units^2 = 56 units^2.
