2. I have no idea how to work out the surface area and volume???
3. Can anyone help me please?
4. To derive the volume of each of them, count the number of cubes; to derive the surface area, count the number of squares on the shapes' surfaces. To get the surface area:volume ratio (if that's what you're after), divide your surface area result from each of them by the volume result.

Thanks for the help. So can you check if this is right. For the first one, the volume is 24 and the surface area I'm not sure. Is it 24? They're the same?! ???

I count 23 - is it possible you counted one of the cubes twice?

For the surface area, you're counting the number of exposed squares on the shape's surface, not the number of cubes - the number of squares on the front, back, sides, top, and bottom of the shape. I hope that makes sense. The number will be quite a bit larger than the volume was.
