The strip is a rectangle of width h, and a length equal to the circumference of each circle (2πr). To find the area of the rectangular sides, use the formula A = lw , where A = area, l = length, and h = height. To calculate the surface area of a rectangular prism. The surface area of any prism is the total area of all its sides and faces. It can also be called as the rectangular parallelepiped. In general, to find the surface area of a rectangular solid, remember that each face is a rectangle, so its area is the product of its length and its width (see the image below). Width is equal to 6 cm. Based on the measurements of the height, width and length you can calculate the surface area and volume of a box. 2. CSA of a cuboid is calculated using the given Curved Surface Area (CSA) Of Cuboid Formula. So again we can determine the total surface area as the sum of the two circles and the rectangular strip. Must be somewhere else in my code then, because it gives me this impossibly huge number starting with 812,649, this calculation is done in a class I made for all the different shape calculations. The surface area is the sum of the areas of all six sides. Hmm I tried that formula in a console application and it worked perfectly. The surface consists of two h x w faces, two h x d faces, and two w x d faces. Rectangular Solids Have Two Different Kinds of Diagonals. The surface area will be the sum of the rectangular base and the #4# triangles, in which there are #2# pairs of congruent triangles. If the Rectangular prism is open from top and bottom then its area is called Area of 4 walls or Lateral surface area. Calculate the total surface area of a regular pyramid if given base perimeter, slant height and base area ( A ) : lateral surface area of a regular pyramid: = Digit 1 2 4 6 10 F For pyramids, where A is the total surface area, p is the perimeter of the base, l is the slant height, and B is the area of the base, the formula is: A = 1 2 p l + B The problem you are attempting to solve has to give you enough information to know the perimeter, p , the slant height, l , and the area of the base, B .
