Who wants to help me on question 41. I don't understand what it means when it says "label a net".
2 answers:
A net is basically a flattened out 3D solid. If you fold all the sides up, you would end up with the 3D model.
What it means by net is an image of the 3d shape if you were to unfold it. Imagine what kind of shape you would get if you were to unfold a cardboard box, for example. Then, after you draw that, it wants you to transpose the measurements of the shape onto the net. I've included an image showing the net of a rectangle prism along with the labels the question asked.
