Usually they do not. The surface areas are part of the solid and so they belong to closed sets.

What properties of solids determine the volumes and surface area?
Resistance to deformation.
How do you find the surface area of ANY 3D solid?
The surface area of a polyhedron can be calculated by first calculating the area of each of its polygonal surfaces and adding these together.The surface area of some curved solids (sphere, cylinder, cone) can be calculated from formula but for most curved solids are more complicated and require integration.
How do you calculate surface area of a parabola?
A parabola is a two dimensional open curve. Its area is therefore infinite.
What are the different terms in solid mensuration?
1. Plane Figures- A flat, closed figure that is in a plane- A plane figure can be made of straight lines, curved lines, or both straight and curved lines.2. Solid Figures- The figures which occupy space are called solids.- Solids are three dimensional figures i.e., they have length, breadth & height.- There are two important facts related to solids-a. Every solid has a surface area. Some solids have plane surfaces, others have curved surfaces.b. Every solid has a 'bulk' & its bulk occupies some space.3. Surface area-It is the sum of areas of all visible (exposed) surfaces of a solid.4. Volume-It is the three dimensional space occupied by a solid, liquid or gas.5. Lateral surface area - is the sum of the surface areas of all its faces excluding the base.6. Total surface area - is the sum of the surface areas of all its faces including the base.
What solids have flat surfaces?
Circles, squares, rectangles, and triangles are solids that have a flat surface.
Why do solids have an open surface while gases not?
Gases also have but it is difficult to detect, air (atmosphere) has an outer open surface.
What properties of solids determine the volumes and surface area?
Resistance to deformation.
How do you find the surface area of two similar solids?
you put: a squared over b squared = surface area of the smaller solid over surface area of the bigger solid

Why do we crush solids before putting them into solvent?
to increase the surface area of the solute
What are formulas for Volume and surface area calculations of various solids?
box:length*breath*height cuboid:same as above
What are the uses of Volume and surface area of solids?
Volume of a solid helps us understand the amount of space it occupy's internally. Surface area of a solid helps us know what is the area of a given face/faces of a solid.
What are the 3 problems of irregular solid?
Difficulty in calculating volume: Irregular solids have complex shapes that do not have simple geometric formulas to calculate their volume. Inaccurate measurements: Due to their irregular shape, measuring the dimensions of irregular solids can be challenging and may lead to inaccurate calculations. Limited surface area formulas: Unlike regular solids, irregular solids do not have standard surface area formulas, making it harder to calculate their surface area.
Why do you crush solids before putting them into a solvent?
Crushing solids increases their surface area, allowing for better contact and interaction with the solvent. This process enhances the efficiency of dissolution, resulting in a faster and more thorough dissolution of the solid in the solvent.
The dimensions of a rectangular solids are 8 Cm and 12 Cm can you tell what the surface area is?
the area of a 2D shape with dimensions 8cm and 12cm is 96cm2, but if you're talking about surface area of a 3D shape then you need the other dimension.
Why do we crush solids before putting them into a solvent?
Crushing solids before putting them into a solvent increases the surface area of the solid particles in contact with the solvent. This allows for better and faster dissolution of the solid into the solvent, leading to more efficient extraction of compounds or dissolution of substances.
Can solids cause pressure?
Yes, solids can exert pressure on the surfaces they come into contact with due to their weight or force applied. This pressure can vary depending on the amount of force exerted and the contact area with the surface.
