The total amount of energy in the universe is

The zero-energy universe hypothesis proposes that the total amount of energy in the universe is exactly zero: its amount of positive energy in the form of matter is exactly canceled out by its negative energy in the form of gravity

Explanation:

hope this helps

Constant.

Explanation:

The total amount of energy and matter in the Universe remains constant, merely changing from one form to another. The First Law of Thermodynamics  states that energy is always conserved, it cannot be created or destroyed.

The zero-energy universe hypothesis proposes that the total amount of energy in the universe is exactly zero its amount of positive energy in the form of matter is exactly canceled out by its negative energy in the form of gravity.

0.3x0.21x0.08kg=mass 1 sheet

mass 500 = 500xmass 1

volume pile = 0.3x0.2x0.048

density=mass/volume= 500xmass 1/0.3x0.2x0.048
