Arectangular block of copper has a mass of 143.584 g and measures 5.05 cm by 2.55 cm by 1.25 cm. find the density of the copper block.

The density of copper block is, 8.92 g/mL

Explanation :  Given,

Length of copper block = 5.05 cm

Breadth of copper block = 2.55 cm

Height of copper block = 1.25 cm

To calculate the volume of copper block by using the formula of volume of cuboid, we use the equation:

where,

V = volume

l = length

b = breadth

h = height

Putting values in above equation, we get:

Conversion used :

Now we have to calculate the density of copper block.

Formula used :

Given:

Mass of copper block = 143.584 g

Volume of copper block = 16.1 mL

Now put all the given values in this formula, we get:

Therefore, the density of copper block is 8.92 g/mL
