To solve this expression, we follow the order of operations: first, calculate the trigonometric functions, then the multiplication and division, and finally the addition and subtraction.

Given:
3*64 1/3 = 192 1/3 = 192.33

Now calculate the trigonometric functions:
-6sin(235) = -6 sin(235) ≈ -6 (-0.5299) ≈ 3.18
-6cos(235) = -6 cos(235) ≈ -6 (-0.8480) ≈ 5.09

Now substitute these values back into the expression:
192.33 + 8 - 3.18 - 5.09

Now perform the addition and subtraction:
192.33 + 8 - 3.18 - 5.09 = 197.15 - 8.27

Therefore, the final answer is approximately 188.88.
