A block of lead has dimensions 4.5 cm by 5.2 cm by 6.0 cm. The block weighs 1587 g. From this information, calculate the density of lead.

d = 11.3 g/cm³

Explanation:

Given data:

Dimensions of lead block = 4.5 cm,5.2 cm, 6.0 cm

Weight of block = 1587 g

Density of lead block = ?

Solution:

Density:

Density is equal to the mass of substance divided by its volume.

Units:

SI unit of density is Kg/m3.

Other units are given below,

g/cm3, g/mL , kg/L

Formula:

D=m/v

D= density

m=mass

V=volume

Volume = 4.5 cm×5.2 cm×6.0 cm

Volume = 140.4 cm³

d = 1587 g/ 140.4 cm³

d = 11.3 g/cm³
