Ask yourself what angle the Center of Mass makes with the bottom corner when it is flat. How much does it need to be tipped then to get it to fall over?

If you need to use vectors and torque equations, then what is the torque at the balance point just before the box tips? That gives you one side of the equation (the torque). What goes into the sin() is not just the ramp angle theta. It is the angle between the gravity vector and the radial vector from the center of gravity to the pivot point that goes into sin(). You need to relate that angle to theta. So some function of theta will be inside the sin().
