What is the density of a cube with a side length of 2 meters and a mass of 40 kg?(1 point)
Responses
60 kgm
60 kgm
120 kg/m2
120 kg/m2
5 kg/m3
5 kg/m3
32 kg/m
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.
What is the volume of a cube with a side length of 3 centimeters?(1 point)
Responses
27 cubic centimeters
27 cubic centimeters
9 square centimeters
9 square centimeters
6 square centimeters
6 square centimeters
3 cubic centimeters
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.

Which term describes the amount of matter in a tree?(1 point)
Responses
the density of the tree
the density of the tree
the height of the tree
the height of the tree
the volume of the tree
the volume of the tree
the mass of the tree
The term that describes the amount of matter in a tree is the mass of the tree.
The density of an object is determined by dividing its mass by its volume. To calculate the density, you need to know the mass and volume of the object. The formula for density is:
Density = Mass / Volume
So, to determine the density, you divide the mass of the object by its volume.
