1. (8 points) The calculation result of the expression $3^{3}+4^{3}+5^{3}+6^{3}+7^{3}+8^{3}+9^{3}$ is
【Solution】Solve: $3^{3}+4^{3}+5^{3}+6^{3}+7^{3}+8^{3}+9^{3}$
$$
\begin{array}{l}
=1^{3}+2^{3}+3^{3}+4^{3}+5^{3}+6^{3}+7^{3}+8^{3}+9^{3}-1^{3}-2^{3} \\
=(1+2+3+\cdots+9)^{2}-1-8 \\
=[(1+9) \times 9 \div 2]^{2}-9 \\
=45^{2}-9 \\
=2025-9 \\
=2016 ;
\end{array}
$$

Therefore, the answer is: 2016.
