6.3.1 Measurement of Polygons & Prisms (a, b, and c are the lengths of the 3 sides) In words, the surface area of a rectangular prism is the area of the six rectangles that cover it. But we don't have to figure out all six because we know that the top and bottom are the same, the front and back are the same, and the left and right sides are the same.he surface area is the areas of all the parts needed to cover the can. That's the top, the bottom, and the paper label that wraps around the middle. You can find the area of the top (or the bottom). That's the formula for area of a circle (pi r2).

Pythagorean theorem The area of a triangle is 1/2sl (side of the triangle times the length or height of the triangle). Because there are four triangles, to find the total surface area, you must multiply by four. Adding all of these faces together yields the equation of surface area for a square pyramid: SA = s2 + 2sl.

Surface Area of Prisms The cross section has the same size and shape as the base, as can be seen in the following diagrams. The surface area of a solid is the total area of all its external faces. To calculate the surface area of a prism we need to: Step 1: Determine the shape of each face. Step 2: Calculate the area of each face. Step 3: Add up all the areas to get the total surface area. We can also use the formula. Surface area of prism = 2 × area of base + perimeter of base × height. Worksheet to calculate the surface area and volume of a rectangular prism. Example: Calculate the surface area of the following prism. Solution: There are 2 triangles with the base = 4 cm and height = 3 cm.

Volume of a triangular prism How to find the volume of a triangular prism. Recall that a prism has two congruent, parallel faces called the bases of the prism. The volume of any prism can be found by multiplying the area of one of the bases by its height. In the case of a triangular prism, each base is a triangle. As a formula where a is the area of one triangular end face, and h is the height.

Lateral & Surface Areas, Volumes The surface area of a figure is the sum of the area of all surfaces of a figure. Surface Area is often abbreviated S.A. The surface area of a prism or cylinder is the lateral area plus the area of each base. Since the bases for a prism or cylinder are congruent, this is often expressed as twice the area of the base. The surface area of a pyramid or cone is the lateral area plus the area of the single base.

- For other prisms, the base and top have the same area and all the other faces are rectangles. In this module, we will examine how to find the surface area of a cylinder and develop the formulae for the volume and surface area of a pyramid, a cone and a sphere.These solids differ from prisms in that they do not have uniform cross sections. This will complete the discussion for all the standard solids.ence, if the radius of the base circle of the cylinder is r and its height is h, then: Volume of a cylinder = π r 2 h. Also in that module, we defined the surface area of a prism to be the sum of the areas of all its faces.
