If for the regular shape we use a formula to calculate it's volume, how we can determine the volume of the irregular shape?

• It is cannot be determined

• By putting it inside the tank containing water. The among increased is the volume of it.

• By using micrometer screw gauge

• By using Vernier scale

What kind of instrument is this and why it used for?

• It is a Vernier Cliper gauge. It is used to measure the length of small scale objects.

• It is a micrometer screw gauge. It is used to measure the volume of small scale objects.

• It is a micrometer screw gauge. It is used to measure the pressure of small scale objects.

• It is a micrometer screw gauge. It is used to measure the length of small scale objects.

Which formula we use to calculate the volume of the Cylinder

• V=lmh

• V=2πr

• V=πr²h

• it can not be determined

Make the correct order from less dense to more dense:

• Liquid, Gas, Solid

• Gas, Solid, Liquid

• Gas, Liquid, Solid

• Gas, Liquid, Gas
