plzz answer these questions
1) what are the boundaries of the surface called as
2) what are the boundaries of the solid called as
3) how many dimensions does a solid have
4) how many dimensions does a surface have
plzzz answer quickly its very urgent​

Answer 1

1. In particular, a surface with empty boundary is a surface in the usual sense. A surface with empty boundary which is compact is known as a 'closed' surface. The two-dimensional sphere, the two-dimensional torus, and the real projective plane are examples of closed surfaces.
2. The boundaries of Solids are surfaces. They have outer boundaries and some solids may have an arbitrary number of inner boundaries. The 3D holes that the inner boundaries define are called "voids".
3. A solid shape have three dimensions namely length, breadth and height. so solid shapes are 3-D figures.
4. This means that doesn't matter that the surface is curved and resides in three dimensions: two dimensions are all that is required, and so the surface is two-dimensional.
