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 can we find the surface area of composite figure?
To find the surface area of a composite figure, first, break it down into simpler shapes (like rectangles, circles, and triangles) whose surface areas you can calculate easily. Measure the dimensions of each individual shape and apply the appropriate surface area formulas. Once you have the surface areas of the individual components, sum them up, making sure to subtract the areas of any overlapping sections if necessary. Finally, ensure that all measurements are in the same units before adding them together.

How do you find the ratio of two similar 3 dimensional figures when only given the surface area?
Notice the exponents in these two statements.Those little tiny numbers tell the whole big story:(the ratio of the surface areas of similar figures) = (the ratio of their linear dimensions)2(the ratio of the volumes of similar solids) = (the ratio of their linear dimensions)3
