What would the world be like without energy?

Well without energy we would have no oil, electricty or anything. I mean we need electricty for computers, phones, ovens, cars and so many more. Energy literlaly powers almost everything in the world! So the world would become a place where everyone would have to do things on thier own. They have to build fires to cook food, they have to wash their own clothes, they have to do all these things on their own instead of relying on electricty!

Hopefully this helps! :)

Multiply the 3 dimensions, assuming it is a rectangular cuboid, to get the volume in cm³ divide mass by volume to get density in g/cm³
