How to calculate the gravity on a hill?

[QUOTE="caspeerrr, post: 5675586, member: 614282"] The question is about a box with no movement standing on a hill. The hill has an angle of 25 degrees. The box has a mass of 40 kg. 1. Calculte the gravity This I still get: F= M x A = 40 x 9,81 = 3,9 x 10^2 The next question tough: 2. Calculate the component Fgravity,x off the gravity alongside the hill. The component I think they ment is marked on the picture included. What I did was 390 / sin(25) because the opposite is known (the gravity) and you want to calculate the hypotenuse. The answer indicates this as the right answer tough: Fgravity,x = Fgravity sin(a) = 165,8 Why do they multiply when you should divide? Am I missing something? Thanks in advance![ATTACH=full]112111[/ATTACH] [/QUOTE]
