A rectangular solid of unknown density is 5 meters long, 2 meters high and 4 meters wide. The mass of this solid is 300 grams. Given this information for this homogeneous (alike throughout) material, calculate its density.

The density of the material is 7.5 g/m^3

Explanation:

The volume of a rectangle is:

Volume = Length*Height*Width

Replacing with data:

Volume = 5 m * 2 m * 4 m = 40 m^3

Density is computed as follows:

Density = Mass/Volume

Replacing with data:

Density = 300 g/40 m^3

Density = 7.5 g/m^3

under a microscope, cancer cells may look very different from normal cells. they often have different sizes and some may be larger than normal while others are smaller. cancer cells are often abnormally shaped and the control centre of the cell (the nucleus) may have an abnormal appearance.
