The density of a cube with a side length of 2 meters and a mass of 40 kg is:
Density = Mass / Volume
Volume = (Side Length)^3
Volume = (2 m)^3
Volume = 8 m^3
Density = 40 kg / 8 m^3
Density = 5 kg/m^3
Therefore, the correct response is 5 kg/m^3.
Density = Mass / Volume
Volume = (Side Length)^3
Volume = (2 m)^3
Volume = 8 m^3
Density = 40 kg / 8 m^3
Density = 5 kg/m^3
Therefore, the correct response is 5 kg/m^3.

The volume of a cube with a side length of 3 centimeters is calculated by cubing the side length:
Volume = (Side Length)^3
Volume = (3 cm)^3
Volume = 27 cubic centimeters
Therefore, the correct response is 27 cubic centimeters.
Volume = (Side Length)^3
Volume = (3 cm)^3
Volume = 27 cubic centimeters
Therefore, the correct response is 27 cubic centimeters.
