Density=mass/volume
Volume= 5.05 x 2.55 x 1.25 = 16.096875 cm^3

Density= 143.584/16.096875 
                                               = 8.919992235 g/cm^3

Answer: 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:

[tex]V=lbh[/tex]

where,

V = volume

l = length

b = breadth

h = height

Putting values in above equation, we get:

[tex]V=5.05cm\times 2.55cm\times 1.25cm=16.1cm^3=16.1mL[/tex]

Conversion used : [tex]1cm^3=1mL[/tex]

Now we have to calculate the density of copper block.

Formula used :

[tex]Density=\frac{Mass}{Volume}[/tex]

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:

[tex]Density=\frac{143.584g}{16.1mL}=8.92g/mL[/tex]

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