Question

the mass of an iron ball is 312g.tge density of iron is 7.8gcmpower3.find the volume of the ball

Answer 1

Answer:

Density, ρ = 7.8 g/cm3  

Mass, m = 312 g  

 

rho space equals space fraction numerator m over denominator V space end fraction space

7.8 space equals space 312 over V

T h u s comma space

V o l u m e comma space V space equals space fraction numerator 312 over denominator 7.8 end fraction space equals space space 40 space c m cubed
