One is composed of organic materials the other is a metal.
Density = (mass) / (volume) Greater density corresponds to either greater mass in the same volume, or same mass in smaller volume. Any way you look at it, rock is the winner, over feathers, balloons, or plastic bottles.

The object with the greatest density is the 20 kilograms of cement, as cement is a dense material compared to feathers, paper clips, and plastic bottles. Density is a measure of how much mass is in a given volume, so the denser the material, the greater the density.
It depends on the density of the material. Think of a 20 ft container filled with feathers and another filled with lead. Do you think they will have the same mass?
20 pounds = 9.07 kilograms.
Yes, it is.
1 kilogram = 2.20462262 pounds20 kilograms = 44.0924524 poundsOn earth, 20 kilograms of mass weighs 44.1 pounds. (rounded)In other places, its weight is different.
20 kilograms = 3.14 stone
20 decigrams is 0.002 kilograms.
A cubic foot is a measure of volume (size). A pound is a measure of weight. The amount of weight that can fit in 20 cubic feet is different for different things. For example, a box with a volume (size) of 20 cubic feet, filled with solid gold, would weigh more than a box with the same size but filled with feathers.
20 pounds is equivalent to approximately 9.07 kilograms.
(0.2 x 20) kilograms = 4 kilograms
