Plz answer ! a platinum bar measures 5.0 cm long, 4.0 cm wide, and 1.5 cm thick. it has a mass of 750.0 grams. don't forget to find the volume of the bar (l x w x h). use the formula d=m/v calculate the density of the platinum bar (you need the volume first). enter your answer in the space provided.

Explanation:

It is given that,

Mass of platinum bar, m = 750 g

Length of the bar, l = 5 cm

Breadth of the bar, b = 4 cm

Width of the bar, h = 1.5 cm

Volume of the bar,

We need to find the density of the platinum bar. The density of any substance is given by :

So, the density of the platinum bar . Hence, this is the required solution.
