Answer
The geometry of $CO_{2}$ is linear with bond angle $180^{\circ}$.
There is no three-dimensional representation of $CO_{2}$.
Work Step by Step
The outer shell electronic configuration of C is $2s^{2}$$2p^{2}$ and the outer shell electronic configuration of O is $2s^{2}$$2p^{4}$ .
Therefore the total number of valent electrons is $$(4\times1)+(2\times6)=16$$
In order to achieve octet configuration we draw covalent bonds between C and two oxygen atoms. Therefore, the Lewis structure for $CO_{2}$ looks as enclosed.
Since C is surrounded by two pairs of electrons it has $sp^{}$ hybridization with bond angle $180^{\circ}$ and linear arrangement.
The oxygen atoms are surrounded by three pairs of electrons, so they have $sp^{2}$ hybridization with trigonal planar geometry and the bond angle less than $120^{\circ}$.
Therefore, the geometry of $CO_{2}$ is linear.
It is not possible to draw three-dimensional representation since $CO_{2}$ has linear geometry.
