C Correct answer
Explanation

The difference in rectangle and cube is that a rectangle is a 2-dimensional figure where the length and the breadth of the geometry are specified.

 A cube is a 3-dimensional figure where the length, breadth and depth of the geometry are specified.

Which of the following is true for the net of a solid?

  1. A geometry net is a 2-dimensional shape that can be folded to form a 3-dimensional shape or a solid.

  2. A net is a pattern made when the surface of a three-dimensional figure is laid out flat showing each face of the figure.

  3. A solid may have different nets.

  4. All of the above

D Correct answer
Explanation
A geometry net is a 2-dimensional shape that can be folded to form a 3-dimensional shape or a solid. Or a net is a pattern made when the surface of a three-dimensional figure is laid out flat showing each face of the figure. A solid may have different nets.
Here are some steps to determine whether a net forms a solid:

1. Make sure that the solid and the net have the same number of faces and that the shapes of the faces of the solid match the shapes of the corresponding faces in the net. 
2. Visualize how the net is to be folded to form the solid and make sure that all the sides fit together properly.

Nets are helpful when we need to find the surface area of the solids.
Thus, all the statements are true.
