#### Question

The mass of an iron ball is 312 g. The density of iron is 7.8 g cm^{-3}. Find the volume of the ball.

#### Solution

Given , Mass M = 312 g

Density d = 7.8 g `cm^-3`

Since , d = `M/V` **⇒ **V = `M/d `

Hence , volume of an iron ball V = `312/7.8` = 40 `cm ^3`

Is there an error in this question or solution?

Solution The Mass of an Iron Ball is 312 G. the Density of Iron is 7.8 G Cm-3. Find the Volume of the Ball. Concept: Measurement of Volume (3d Concept).
