Answer:

160 units^2

Explanation:

Each of the four triangular faces has an area of ...

A = (1/2)bh = (1/2)(8)(6) = 24 . . . square units

The square base has an area of ...

A = s^2 = 8^2 = 64

Then the total surface area is ...

A = base area + 4 · triangle area

A = 64 + 4(24) = 160 . . . square units
