Question

A block of lead has dimensions of 4.50 cm by 5.20 cm by
6.00 cm. The block weighs 1590g. Calculate the density
of lead.​

Answer 1

Answer:

$0.01132 g/mm^{3}$

Explanation:

Density, $\rho=\frac {m}{v}$

Where m is the mass of the object and v is the volume of the same object

Given the dimensions, we can make them in mm hence 45 mm by 52 mm by 60 mm

Volume=45*52*60= 140400 mm^{3}

Density, $\rho=\frac {1590}{140400}=0.011324786 g/mm^{3}\approx 0.01132 g/mm^{3}$
