Strain as Ratio of Two Lengths

Note that strain is another length-related engineering variable. 

The important role of area in the design of varions systems. 

Each cube now has an exposed sur ce area of 1.5 m, which amounts to a total exposed surface area of 12 m.  

Let us proceed with dividing the dimensions of our 1 m X ImX 1 m or nal cube into even smaller cubes with the dimensions of 0.25 m X 0.25 m X 0.25 m. We will now have 64 smaller cubes, and we note that the total volume of the cubes is sdll 1 m. However, the surhux area of each cube is 0.375 m, leading to a total surface area of 24 m. Thus, the same cube divided into 64 smaller cubes now has an exposed suthice area that is four times the oi%i-nal surfoce area.
