Question

A 94 g sample of iron has a length of 2 cm, width of 3 cm, and a height of 2 cm. What is its density?

Answer 1

volume of iron =[2*3*2]cm^3

mass[given]=94g

hence,

density=mass/volume

=94/2*3*2 g cm^-3

=94/12 g cm^-3

=7.8333~7.8 g cm^-3

Answer 2

As given data

Volume of iron(v) =l×b×h

Density =?

Mass =94

Volume = 3×2×2=12

Density = M/V

= 94/12 = 7.83
