No idea please l need an answer
water density =1000 kg/m^3
so
steel density = 7800 kg/m^3
volume of this cube = (0.10)^3 = 10^-3 m^3
so mass =7800 * 10^-3 = 7.8 kg
so
steel density = 7800 kg/m^3
volume of this cube = (0.10)^3 = 10^-3 m^3
so mass =7800 * 10^-3 = 7.8 kg
Relative density of a substance= density of that substance/ density of water
7.8=density of steel/ 1000
density of steel=7.8×1000 =7800kg/m^3
volume=10×10×10
=1000cm^3
1000/1000000= 0.001m^3
mass=density×volume
=7800×0.001
=7.8kg
7.8=density of steel/ 1000
density of steel=7.8×1000 =7800kg/m^3
volume=10×10×10
=1000cm^3
1000/1000000= 0.001m^3
mass=density×volume
=7800×0.001
=7.8kg
