Why are little pieces of cardboard lighter than a whole piece of cardboard?

I use small cardboard boxes for organizing drawers, etc,---also break them down and use it in the garden to kill weeds, and I add some to my compost. ... side to one edge that's somewhat shorter than the magazine, to enable one to remove one magazine without removing the whole box from the shelf.

This is because little pieces of cardboard is the same thing as splitting the weight, so splitting the weight of it means the total of all the pieces won't be exactly the same as a whole cardboard.

This is what i found on google “when one phosphate group is removed by breaking a phosphoanhydride bond in a process called hydrolysis, energy is released, and atp is converted to adenosine diphosphate (adp). likewise, energy is also released when a phosphate is removed from adp to form adenosine monophosphate (amp).” i hope this you .
