The volume of a cube with a side length of 3 centimeters is calculated by cubing the side length. Therefore, the volume of the cube is 27 cubic centimeters.
The amount of matter the object has is not provided. In order to determine the amount of matter or mass, additional information such as the density of the material the cube is made of would be required.
The compactness of an object refers to the ratio of its mass to its volume. Without the information about its mass or density, it is not possible to determine how compact the cube is.
The amount of space that the object takes up is equivalent to its volume, which is 27 cubic centimeters.
The weight of the object is not provided. The weight of an object depends on its mass and the gravitational force acting on it. Additional information such as the density of the material and the acceleration due to gravity would be needed to calculate the weight.
