1. \(1\)
2. \(2\)
3. \(3\)
4. \(4\)
In which of the following, the number of significant figures is different from that in the others?
1. \(2.303~\text{kg}\)
2. \(12.23~\text{m}\)
3. \(0.002\times10^{5}~\text{m}\)
4. \(2.001\times10^{-3}~\text{kg}\)
The mass and volume of a body are \(4.237~\text{grams}\) and \(2.5~\text{cm}^3\), respectively. The density of the material of the body in correct significant figures will be:
1. \(1.6048~\text{grams cm}^{-3}\)
2. \(1.69~\text{grams cm}^{-3}\)
3. \(1.7~\text{grams cm}^{-3}\)
4. \(1.695~\text{grams cm}^{-3}\)
The number of significant figures in \(0.0006032\) m2 is:
1. \(4 \)
2. \(5\)
3. \(7\)
4. \(3\)
What is the number of significant figures in \(0.310\times 10^{3}?\)

Each side of a cube is measured to be \(7.203~\text{m}\). What are the total surface area and the volume respectively of the cube to appropriate significant figures?
1. | \(373.7~\text{m}^2\) and \(311.3~\text{m}^3\) |
2. | \(311.3~\text{m}^2\) and \(373.7~\text{m}^3\) |
3. | \(311.2992~\text{m}^2\) and \(373.7147~\text{m}^3\) |
4. | \(373.7147~\mathrm{m^2}\) and \(311.2992~\text{m}^3\) |
If \(97.52\) is divided by \(2.54\), the correct result in terms of significant figures is:
1. | \( 38.4 \) | 2. | \(38.3937 \) |
3. | \( 38.394 \) | 4. | \(38.39\) |
The decimal equivalent of \(\frac{1}{20} \) up to three significant figures is:
1. | \(0.0500\) | 2. | \(0.05000\) |
3. | \(0.0050\) | 4. | \(5.0 \times 10^{-2}\) |
The numbers \(2.745\) and \(2.735\) on rounding off to \(3\) significant figures will give respectively,
1. | \(2.75\) and \(2.74\) | 2. | \(2.74\) and \(2.73\) |
3. | \(2.75\) and \(2.73\) | 4. | \(2.74\) and \(2.74\) |
1. | \(9.98\) m | 2. | \(9.980\) m |
3. | \(9.9\) m | 4. | \(9.9801\) m |
