Graphical solution to vectors

Question

I have completed a task, and now need to create a graphical solution. This is where i am stuck. As i have i,j and k. Is this because its 3D? As i have only seen 2 whilst looking for a solution.

This is my competed answer. I am just looking for help to represent this graphically.

The body is in equilibrium because: $$(6i + 7j – 5k) + (-18i – 38j – 14k) + (-18i + 25j + 24k) + (30i + +6j – 5k) = 0i + 0j + 0k = 0$$

I have this:

Is this correct? If not what have i done wrong? And how do i finish it to look like yours?
