1. a
2. none
3 c
4.b
Here, we want to match the respective solid with the net
1) This net is for the the option A which is the cube
This is so because, a cube is a solid shape with all sides being equal. So what this mean is that the net that will form a cube should be composed entirely of squares which we of course have in the first net
2) This does not match any of the solid shape and the correct option here should be none
3) This is the net for shape c
Shape c is a cylinder. A cylinder consist of 2 parallel and circular openings which are separated by a rectangular crossection
4) This is the net for shape b
shape b is a cuboid. It is the rectangular version of a cube with the nets being rectangles (6 rectangles) instead of cubes as in the case with the net of a cube with 6 squares
