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.
What solids have flat surfaces?
Circles, squares, rectangles, and triangles are solids that have a flat surface.
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.
How do you calculate surface area of a parabola?
A parabola is a two dimensional open curve. Its area is therefore infinite.
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
Why do we crush solids before putting them into a solvent?
to increase the surface area of the solute
How are surface area and volume related to cell size?
Volume varies as the 1.5th power of the surface area of regular solids. With other well behave solids, this relationship applies as long as all three dimensions change in the same ratio - that is, the shapes are similar.
What are formulas for Volume and surface area calculations of various solids?
box:length*breath*height cuboid:same as above
Why do you crush solids before putting them into a solvent?
To increase the surface area of the solute, which allows it to dissolve faster.
Methods to improve the reactivity of solids?
Reactivity of solids can be increased by increasing the surface area (ie. using powdered form of the solid), increasing temperature in oreder to break the bonds, adding catalyst to enhance the reaction,
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.
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.
