We are asked to **determine the density of lead (in g/cm ^{3} )** in

Recall that ** density** is the ratio of the mass and volume of an object:

$\overline{){\mathbf{density}}{\mathbf{=}}\frac{\mathbf{mass}}{\mathbf{volume}}}$

Also, the ** volume of a rectangle **is given by:

$\overline{){\mathbf{V}}{\mathbf{=}}{\mathbf{L}}{\mathbf{\times}}{\mathbf{W}}{\mathbf{\times}}{\mathbf{H}}}$

where:

**L** = length

W = width

H = height

What is the density of lead (in g/cm^{3} ) if a rectangular bar measuring 0.50 cm in height, 1.55 cm in width, and 25.00 cm in length has a mass of 219.1 g ?
