How do you calculate the area of a pyrimid?

Answer 1

A pyramid has 5(five) faces. Made up of 4 trigular faces and a square base .

You need to know the length of the square base and the length of a sloping face , from the top of the pyramid to the centre of the base line.

Hence

Area of triangl;e = 0.5 X sloping length X base)

Area of the four triangles = 4 X 0.5 X sloping length X base)

Area of base = length X length . = length^(2)

Hence the area of the pyramids faces = 4 X 0.5 X sloping length X base + length^(2)

NB Notice this last term is 'added' , not multiplied.
