\[\boxed{\ \mathbf{1491}\mathbf{\ (1199)}.\ Еуроки\ - \ ДЗ\ без\ мороки}\]
\[V_{I\ куба} = a_{I}^{3};\ \ \ \ \ a_{\text{II}} = 3a_{I}\]
\[V_{ІI\ куба} = a_{ІІ}^{3} = \left( 3a_{І} \right)³ = 27a_{І}^{3}\]
\[в\ \ \ \ \frac{V_{\text{II}}}{V_{I}} = \frac{27a_{I}^{3}}{a_{I}^{3}} = 27\ раз\ больше.\]
\[Ответ:в\ 27\ раз.\]
