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
Reveal answer Fill a bubble to check yourself
D Correct answer
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 volume of a stone can be determined by the displacement method using a measuring cylinder. True or false.

  1. True

  2. False

A Correct answer
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.

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
Reveal answer Fill a bubble to check yourself
C Correct answer
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
Reveal answer Fill a bubble to check yourself
B Correct answer
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
Reveal answer Fill a bubble to check yourself
A Correct answer
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.
