Find the density of a solid object whose mass is 315g, given that its length is 7cm, width is 3cm and height is 5cm. b) State the unit for measuring density.
Thanks for helping

Explanation:

given

mass (m) = 315 g

length (l) = 7 cm

width (b) = 3 cm

height (h) = 5 cm

Now

volume (v) = l * b * h

V = 7 * 3 * 5

V = 105 cm³

Density (d) = ?

We know

density is defined as mass per unit volume so

d = m / v

d = 315 / 105

d = 3 g/cm³

Therefore density = 3 g/cm³

Note

If the question is asked to write in SI unit of density then u have to write the unit of density as kg/m³

Hope it will help :)

Fermentation is a metabolic process in which an organism converts a carbohydrate, such as starch or a sugar, into an alcohol or an acid. For example, yeast performs fermentation to obtain energy by converting sugar into alcohol. Bacteria perform fermentation, converting carbohydrates into lactic acid. The study of fermentation is called zymology i think lol
