Question

calculate the density of a metal block of dimensions 5×3×10cm having a mass of 40g

Answer 1

Density = Mass/Volume

So,

Mass = 40 g

Volume = 5 x 3 x 10 = 150 $cm^{3}$

Density = 40 g /150 $cm^{3}$

Density = 0.266 g/ $cm^{3}$.

Answer 2

density=mass/volume

volume=5×3×10=150cm³

mass=40g

density=40/150=0.26
