Question

a block of glass is 30 cm long,25cm wide and has thickness of 2 cm.find the density if mass is 7500g?

Answer 1

Answer:0.5 kg/m (cube)

Explanation:

volume (v)= (30*25*2) cm

            = 1500 cm/100 m

            = 15m

mass (m) = 7500g/1000kg

            =7.5 kg

     Density = m/v

                    = 7.5/15

                     = 0.5 kg/m (cube)
