 Mass(Kg) Volume (m3) Density(kg/m3) 350 175 - - 190 4

 Density of Metal (kg/m3) Density of water (kg/m3) Relative Density 103 5 8.5 × 103 103 -

 weight(N) Area (m2) Pressure(Nm−2) - 0.04 20,000 1500 500 -

#### Solution

We know, "Density" = "Mass"/"Volume"

So, using the above formula, we can find one quantity if the other two quantities are given.

 Mass (kg) Volume (m3) Density (kg/m3) 350 175 2 760 190 4

We know, Relative density of substances ="Density of substances"/"Density of Water"

So, using the above formula, we can find one quantity if the other two quantities are given.

 Density of Metal (kg/m3) Density of water (kg/m3) Relative Density 5 × 103 103 5 8.5 × 103 103 8.5

We know, Pressure = "Force"/"Area"

So, using the above formula, we can find one quantity if the other two quantities are given.

 Weight (N) Area (m2) Pressure (N m−2) 800 0.04 20,000 1500 500 3
