How to calculate v=4/3pi(1.5 cm)3

$${\mathtt{v}} = \left({\frac{{\mathtt{4}}}{{\mathtt{3}}}}\right){\mathtt{\,\times\,}}{\mathtt{\pi}}{\mathtt{\,\times\,}}{{\mathtt{1.5}}}^{{\mathtt{3}}} \Rightarrow {\mathtt{v}} = {\mathtt{14.137\: \!166\: \!941\: \!154\: \!069\: \!6}}$$

 and the result is in cm³
