The surface area of a pyramid can be calculated by adding the area of the base to the sum of the areas of the triangular faces. If the base of the pyramid is a regular polygon, each of the ...

The area of the base is \(5 \times 5 = 25~cm^2\) The area of each triangular face is \((5 \times 6) \div 2 = 15~cm^2\). There are four identical triangular faces, so the total surface area is \(25 ...

For a pyramid to look like a pyramid, each of the four triangular-shaped sides must slope up and towards each other at the same angle so that they meet at a point at the top. The builders ...
