Answer 1

The surface area of the monument shaped like a square pyramid is 14 m².

Area

Area is the amount of space that is occupied by a two dimensional shape or object.

From the diagram

Area of each triangle = (1/2) * base * height = (1/2) * 2 * 2.5 = 2.5 m²

Area of square = length * length = 2 m * 2 m = 4 m²

Surface area of monument = 4(2.5) + 4 = 14 m²

The surface area of the monument shaped like a square pyramid is 14 m².
