Yes. Your feasible region is a convex (bounded) polytope, which means that every point in the feasible region can be written as a convex combination of extreme points. Let's say that your function is $f()$, the maximum occurs at $\bar{x}\in [0,1]^n$, and $\bar{x} = \sum_{i=1}^k \alpha_i x^{(i)}$, where the $x^{(i)}\in [0,1]^n$ are extreme points of the ...

The problem is infeasible:
$(c_1,c_2) \Rightarrow x_1=1$
$(c_3,c_4) \Rightarrow x_2+x_3=2$
$(c_1,c_2,c_7) \Rightarrow x_4 + x_5 \le 2$
$(c_5,c_6) \Rightarrow -(x_2+x_3)+0.4(x_4+x_5) \ge 2 \text{ and so } (c_3,c_4,c_5,c_6)\Rightarrow x_4 + x_5 \ge 10$
The last two lines are not consistent. Note that we also obtain a conflict with $(c_8,c_9)$:
$(c_8,c_9) \...
