You will be using these rules in your calculations. As an example of a sample calcu find the volume of a rectangular solid: V = Lx W x H V = (25.95 cm)(5.87 cm)(83 cm) V = 13000 cm³ = 1.3 x 104 cm3 %3D with %3D Note that when you do this calculation in your calculator, you will have an answe 12643.0995. However, the 83 cm limits your answer to 2 significant figures, so y ound the final answer to 2 significant figures. Remember you need to keep the f the sidnificant figures! The scientific notation helps clarify that none of the ze

Units and Dimensions

These are generally defined as the terms which precede or describes the dimensions further. These are also further divided into two parts namely fundamental units and the derived units.
