I have an upcoming exam that is essentially a review of all the math that I've done from Grade 1 to Grade 12. I'm currently working on reviewing for it, but I'm struggling with the geometry section because I cannot remember any geometry whatsoever, and I have no clue where to start with the geometry problems on the practice worksheet that I've been given.
If anyone knows how to solve the problems on the photo attached to this post, I would greatly appreciate your help.

For figure 1, you can count the cubes.
You could also break the figure down into rectangular blocks, and remember the the volume of a rectangular prism (the fancy name for a block) is length x width x height.
For figure 2, you need to determine the side length of the square. What do you know about the diameter of the circle?
For figure 3, you only need to know the volume of a circle, which is (pi)(r^2). r is the radius.

Would 3 x 3 x 6 still work on figure 1 even though it's a staircase that loses blocks as you go higher as opposed to a normal rectangular prism?

I think that the diameter of a circle is equal to the side length of a square? And the diameter of a circle is equal to two times the radius

3x3x6 counts all the blocks that are missing.

Good. Can you find the area of the square now?
