An ancient square pyramid is 60 m tall and 200 m one each side at the base. The density of the building stone is 1300 kg/m3. If the pyramid is solid throughout, what is the pyramid's approximate mass

it doesn't. it was imagined up in the middle ages.

it was given as a lesson and guide for prayer.

it's when something is going so fast it makes a loud noise, breaking the sound barrier, for example: a jet makes a loud noise, not only cause of the jet but because they reached a point where they went so fast that you can year the noise from various parts, kinda like a police car, lets say the car was going   so fast that you hear the siren of the cop car right next to you, but the car is probably a mile a way, it's cos the siren was next to you a few seconds if you understand me
