Similar Solid Comparison Worksheets

How to Compare Similar Solids? The solid is anything having volume and surface area. You may have the idea of similar solids. By now, we can compare all such objects if we are able to find their volume and surface area. Here is a way to discover how shapes are similar to each other. Instead of going into the history of complex formulae and fall into confusion, let’s discuss an easier way to compare similar solids. The similar solids may have the same shape and are congruent, but they may differ in size. We go on comparing on their edges instead of how they look. What we need now is a way to relate everything together. We can compare and contrast volumes and surface areas, but we will only get caught in a web of formulas and confusion. Here is an example of the pyramids. If the ratio of measures of the pyramids is the same for all the different measures in both solids, the two are similar.

The ratio of the heights should equal the ratio of the base lengths. Basically, every measurement should have the same ratio, called the scale factor.
