Answer:

96 cm²

Explanation:

The surface area of a pyramid is the sum of the base area and the area of the four triangular faces. Using the formulas for each of these, a simplified formula can be written.

A = s(s +2h)

where s is the side length of the square base, and h is the slant height of a triangular face.

__

For the given dimensions, s=4 cm, h=10 cm, the surface area is ...

A = (4 cm)(4 cm +2×10 cm) = (4)(24) cm²

A = 96 cm²

The surface area of the pyramid is 96 square centimeters.
