Ablock 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.

Explanation:

Density,

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,

the closer the planet is to the sun, the larger the gravity
