Answer 1

800

Explanation:

The surface area of a pyramid is the sum of the areas all faces.

The triangles are congruent, with bases 16 inches and heights 17 inches, so the area of each triangle is

`16\cdot 17\cdot (1)/(2)=136~\text{in}^2.`

Since there are four triangles, the combined area of them is

`136\cdot 4=544~ \text{in}^2`.

The area of the square base is
`16\cdot16=256~\text{in}^2`, so the total area of all faces is
`544+256=\boxed{800~\text{in}^2}`.
