Ametal cube has a mass of 18g and a volume of 2cm3. what is the density of the cube?

Density=9g/cm^3

Mass per unit volume  of a substance is known as density

density = mass/volume.

D=m/v

mass = 18g

volume= 2cm^3

d=  18/2

D= 9g/cm^3

starchy vegetables are high in carbohydrates.

starchy vegetables contain more carbohydrates than non-starchy vegetables.

explanation:

there are two primary categories of carbohydrates, essentially differentiated on the basis of their carbohydrate content (which is in the form of starch - a complex carbohydrate):

those vegetables which contain little amounts of starch are termed as non-starchy vegetables, and some examples include: artichokes, broccoli and bean sprouts.

vegetables high in their starch content are distinguished as starchy vegetables, and some examples include: potatoes, chickpeas and corn.
