What is the total surface area of the square pyramid? A square pyramid. The square base has side lengths of 8 inches. The triangular sides have a height of 5 inches. square inches 20 40 104 144

9514 1404 393

  144 square inches

Step-by-step explanation:

The total surface area is the sum of the areas of the square base and the four triangular faces. Using b for the base length and h for the triangle height, the area is ...

  SA = b² +4(1/2)bh = b(b +2h)

For the base of 8 inches and the height of 5 inches, the total area is ...

  SA = (8 in)(8 in + 2·5 in) = 8·18 in²

  SA = 144 in²
