\(15^3+5.15^2-5^3.\frac{1}{8}^3+6.18^2-6^3\)
\(=15^2.\left(15+5\right)-\left(5.\frac{1}{8}\right)^3+6.\left(18^2-6^2\right)\)
\(=225.20-\left(\frac{5}{8}\right)^3+6.\left(324-36\right)\)
\(=4500-\frac{125}{512}+6.288\)
\(=\left(4500+1728\right)-\frac{125}{512}\)
\(=6228-\frac{125}{512}\)
\(=...........\)
