Plane developments of geometric bodies (1): Nets of prisms A right prism is a polyhedron that has two congruents pararel polygonal faces (bases of the prism) and with all remaining faces are rectangles. The main interest of this page is to see how a right prism can be developed into a plane net. There is a platonic solid that is a prism, the cube. This is a cube net: The lateral surface area of a prism is the sum of the areas of the rectangles that form the faces that are not bases of the prism. We can calculate the lateral surface area of a right prism (p is the perimeter of a base and h is the height of the prism):

Adding Fractions with the Same Denominator Adding fractions with the same denominators is pretty straightforward when you follow the rules. This lesson covers adding fractions with same denominator. We will include all of the information you will need to make working with common denominator problems a breeze! The equation above shows the Rule for addition. So, if your are dealing with the same (common) denominator (b), the answer is the sum of the numerators (a and c) over their common denominator.
