Question

A block of iron has the dimensions of 3.00 cm x 3.00 cm x 3.00 cm. It has a mass of 213 g. Water has a density of 1.00 g/cm3. Will it sink in water?

A). Yes
B). No

Answer 1

You find the density like this:

213/3^3 = 7.8889 g/cm^3

Yes it will sink, as 7.8889 > 1

Answer 2

Answer: Yes it will sink.

Step-by-step explanation

`Density= (mass)/(volume)`

If the density of a substance in less than of the another substance then the substance with less density will float in substance with higher density or vice versa.

Density of iron block:

mass of iron = 213 g

Volume of block = length× breadth×height=
`{3.00 cm* 3.00 cm* 3.00 cm}`

`\rho_(iron)=(mass)/(volume)=(213 g)/(3.00 cm* 3.00 cm* 3.00 cm)=7.8 g/cm^3`

Density of the water =
`\rho_(water)=1.00g/cm^3`

The
`\rho_(iron)>\rho_(water)`, density of iron block is more than of the water which means that iron block will get sink in the water.

So, yes it will sink.
