Question

An iron piece has dimensions 3 cm x 2 cm x 5 cm whose mass is 63 g. Find the density of the body in CGS and SI units.​

Answer 1

Answer:

So,

Volume of Iron piece= (3 x 2 x 5) cm3

                                    = 30 cm3. = 0.00003m3

Mass= 63g = 0.063g

Density in C.G.S unit = M/V = 63/30 = 2.1g/cm3

Density in S.i Unit = M/V =  0.063/0.00003 = 2100kg/m3
