# The volume of a cube is $1.83 \;cm^3$. Find the volume of $25$ such identical cubes to correct number of significant figures.

$(a)\;45.9 \quad (b)\;45.75 \quad (c)\;46 \quad (d)\;45.8$

Total volume $=25 \times 1.83$
The number of significant figure is $3$ in $1.83$ and $25$ is not a meaured quantity
Hence the correct option is $d$
