Acube made of an unknown material has a height of 9 symeters the mass of this cube is 3645 g. calculate the density of this cube given this information

Explanation:

The density of a material is given by:

(1)

Where:

is the mass of the cube

is the volume of the cube

Now, the volume of a cube is equal to the length of its edge to the power of 3:

(2)

If we know , the volume of this cube is:

(3)

Substituting (3) in (1):

(4)

This is the density of the cube

the answer would most likely be c, because if it's a comical piece of information, it may likely not be true, if it's a site that allows anybody to edit the content, it could mean a five year old is typing the info, and if it's a tv show produced by a celeb, it may have a biased opinion.
