We are open to collaborations of all types, please contact Andy at for all enquiries. The clear explanations, strong visuals mixed with dry humor regularly get millions of views. Andymath content has a unique approach to presenting mathematics. Now since it is composed of all rectangular faces, and the area of a rectangle is given by the product of its length and width, add up all the products of lengths and breadths to conjure up the surface area of a rectangular prism. Solution: Given side length of cube 4 inches. Example 3: Using the surface area formula of the cube find the surface area of the cube whose side is 4 inches. The surface area of cone will be 282.6 inches2. A rectangle is a special type of quadrangle where all the interior angles are equal to 90° and all opposite sides are the same length. A rectangle is a four-sided figure with all interior angles are right angles and opposing sides have equal lengths. Visit me on Youtube, Tiktok, Instagram and Facebook. The surface area of a rectangular prism is equal to the sum total of the surfaces areas of all its faces. The total surface area formula of cone T r (r + l) 3.14 × 6 × (6 + 9) 282.6 inches 2. Rectangle Perimeter and Surface Area Formulas. In the future, I hope to add Physics and Linear Algebra content. Topics cover Elementary Math, Algebra, Geometry, Algebra 2/Pre-calculus/Trig, Calculus and Probability/Statistics. If you have any requests for additional content, please contact Andy at He will promptly add the content.
