Don't worry there are no such things as stupid questions! I should have been more clear when I was typing.
So for the object you want to rotate it should ideally be something that you want to study or are interested in. For example, say I wanted to study the torso of a human. I would first draw it facing the front and then rotate it a little each time to the right / left / up / down just like the rotated boxes exercise https://drawabox.com/lesson/1/rotatedboxes . I would do this to get a sense of how that object is rotated / sits in 3d space and it would give me a greater understanding of that object. Another benefit of doing this is that it allows you to rotate the object in your mind which helps when you draw it in the future, thats why doing rotations of human anatomy is useful if you were going to draw humans because it would allow you to see how it appears from different angles. The main thing to watch out for is that you don't want to get too detailed in your drawings because this exercise is more about gaining a greater understanding of an object and not trying to draw it beautifully. So try to simplify what you are drawing such that you can still gain a sense of rotation while not making it so simple that you gain nothing from doing this exercise. Here are some examples of what that would look like https://imgur.com/a/YGuebqN . The key to making this work is by already having the knowledge of how to draw the object you want, this exercise will increase your understanding of that object and how it sits in 3d space.
Another example could be that you are very interested in cars, you would then find car references and then draw cars like the rotated boxes exercise (Note: this would probably be the hardest thing to rotate).
When / If you get to lesson 6 and 7 you will realize that anything in this world can fit into a box and so anything can be rotated which makes this exercise a good test of your understanding of an object and how it sits in 3d space.
All that matters is that you choose something you want to know more about / are interested in and then you rotate it. Also remember that this is only one exercise, and pretty much anything (from lesson 3 onwards) on the drawabox website will test and deepen your understanding of 3D space.
I hope this clarifies things a bit and don't hesitate to ask more questions if you are still unsure.
