If the length of a rectangular plate is $1.5\, cm$ and the width is $1.203\, cm$, then its area is ............ $cm^2$.

Keeping the significant figures in view,the sum of the physical quantities $52.01 \ m$,$153.2 \ m$,and $0.123 \ m$ is: (in $m$)

The radius of the Earth is $6371 \ km$ and the radius of its orbit around the Sun is $149 \times 10^6 \ km$. The order of magnitude of the diameter of the orbit is greater than that of the Earth by

The length,breadth,and thickness of a metal sheet are $4.234 \; m$,$1.005 \; m$,and $2.01 \; cm$ respectively. Then the area and volume of the sheet are:

An object of mass $4.237 \, g$ occupies a volume of $1.72 \, cm^3$. The density of the object to appropriate significant figures is ......... $g \, cm^{-3}$.

$A$ substance of mass $49.53 \ g$ occupies $1.5 \ cm^3$ of volume. The density of the substance (in $g \ cm^{-3}$) with the correct number of significant figures is:
