The outer structure of the building has been completely renovated and the interior decorators will be starting inside next week.

Diện tích đáy bé: \(S = {3^2} = 9\). Diện tích đáy lớn: \(S' = {9^2} = 81\). Chiều cao \(h = 12\).

Thể tích khối chóp cụt tứ giác đều là:

\(V = \frac{1}{3}h\,\left( {S + S' + \sqrt {S \cdot S'} } \right) = \frac{1}{3} \cdot 12\left( {9 + 81 + \sqrt {9 \cdot 81} } \right) = 468\,\,\,{\rm{(c}}{{\rm{m}}^{\rm{3}}}{\rm{)}}\). Chọn D.

Ta có \(f'\left( x \right) = \frac{1}{{x - 1}}\)\( \Rightarrow f\left( x \right) = \int {\frac{1}{{x - 1}}} \;{\rm{d}}x\) \[ = \ln \left| {x - 1} \right| + C = \left\{ \begin{array}{l}\ln \left( {x - 1} \right) + {C_1}\,\,{\rm{khi}}\,\,x > 1\\\ln \left( {1 - x} \right) + {C_2}\,\,{\rm{khi}}\,\,x < 1\end{array} \right.\].

Mặt khác \(\left\{ \begin{array}{l}f\left( 0 \right) = 2022\\f\left( 2 \right) = 2023\end{array} \right. \Leftrightarrow \left\{ \begin{array}{l}{C_2} = 2022\\{C_1} = 2023\end{array} \right..\) Vậy \[f\left( x \right) = \left\{ \begin{array}{l}\ln \left( {x - 1} \right) + 2023\,\,{\rm{khi}}\,\,x > 1\\\ln \left( {1 - x} \right) + 2022\,\,{\rm{khi}}\,\,x < 1\end{array} \right.\].

Do đó \(S = f\left( 3 \right) - f\left( { - 1} \right) = \ln 2 + 2023 - \ln 2 - 2022 = 1.\) Chọn C.
