Questions Related to measurement of volume

$1000l$ = ?

  1. $1ml$

  2. $1m^3$

  3. $1cm^3$

  4. $1000m^3$


Correct Option: B
Explanation:

$1000l=1m^3$. $l$ is used to measure the volume of a fluid and $m^3$ is generally used to express volume of a solid.

$\displaystyle 1{ m }^{ 3 }$ = ?

  1. $10^6cm^3$

  2. $\displaystyle 1{ cm }^{ 3 }$

  3. $10^{-6}cm^3$

  4. None of these


Correct Option: A
Explanation:

$1m=100cm=10^2{cm}$

So, $1m^3=({10^2})^3cm^3=10^6cm^3$

Which is the correct form of expressing SI unit of volume?

  1. $\displaystyle { m }^{ 3 }$

  2. $cubicmetre$

  3. $\displaystyle { metre }^{ 3 }$

  4. all of these


Correct Option: D
Explanation:

SI unit of volume is $m^3$ which can also be written as $cubicmetre$ and $metre^3$. It is a big unit, the smaller units are also in use.

The space occupied by a body is called its

  1. area

  2. volume

  3. mass

  4. none of these


Correct Option: B
Explanation:

The space occupied by a body is called its volume. SI unit of volume is $m^3$.

The volume of a liquid is expressed in

  1. $l$

  2. $l^3$

  3. $m^3$

  4. $kg$


Correct Option: A
Explanation:

The volume of liquids is expressed in $litre(l)$.

The volume of a stone can be determined by the displacement method using a measuring cylinder. True or false.

  1. True

  2. False


Correct Option: A
Explanation:

It is true that the volume of a stone (or any irregular shaped body) can be determined by the displacement method using a measuring cylinder. Volume of the stone is equal to the difference of final level of water in the mesuring jar and the initial level.

Name the unit in which the volume of liquid is generally measured. How can this unit is related to L.

  1. kilogram, 1 litre = 10$^{-6}$ m$^3$

  2. litre, 1 litre = 10$^{-6}$ m$^3$

  3. litre, 1 litre = 10$^{-3}$ m$^3$

  4. litre, 1 litre = 10$^{-3}$ cm$^3$


Correct Option: C
Explanation:

Volume is generally measured in liter, $1\ liter=10^{-3}m^3$

Mark the formulae which is used to measure volume of a regular shaped object.

  1. Volume of a cuboid $=$ Length $\times$ Breadth $\times$ Height

  2. Volume of a cube of side $a$ each, $V = {a}^{3}$

  3. Both A and B

  4. None of A and B


Correct Option: C
Explanation:

If the length, breadth and height are equal, a cube is formed. Let $a$ be the length of each side of the cube, then its volume $V$ is equal to $a \times a \times a$, or ${a}^{3}$.

Volume of a cube of side a each, $V  = {a}^{3}$

The volume of a cuboid of length $\left(l\right)$, breadth $\left(b\right)$ and height $\left(h\right)$, is the product of length, breadth and height.

Volume of a cuboid $=$ Length $\times$ breadth $\times$ Height

The space occupied by a substance is its

  1. Area

  2. Volume

  3. Surface area

  4. Cross section area


Correct Option: B
Explanation:

The space occupied by a substance is its volume. The $SI$ unit for volume is the cubic metre $\left({m}^{3}\right)$.

Sub-multiples of the cubic metre, the cubic centimetre and the cubic millimetre are used for smaller measurements.

In a burette, the zero mark on the graduation scale is near its mouth.

  1. True

  2. False


Correct Option: A
Explanation:

A burette is a device used in labs (chemistry) for the dispensing of variable, measured amounts of liquids or solutions. A graduated volumetric burette delivers measured volumes of liquid. Hence, a burette determines the difference between the initial and final volumes of liquid. Therefore the scale on burette is marked downwards(zero at the top), so as to measure correct amount of volume delivered.
Hence, given sentence is true.
