Why were pyramids built in the shape that they were?
Egyptologists have many different theories as to why pyramids were built in this odd shape.
Three of them are :-
1. Pyramids represented the first land to appear at the beginning of time - a hill they called 'Ben-Ben'.
2. The sloping sides of the pyramid allowed the dead pharaoh to climb to the sky and live forever.
3. The shape represented the rays of the sun.
