Area of prism math. Surface area of prism 2 x area of the base perimeter of the base x height. The actual formula to find out the circumference is used depending upon the shape of the base. Surface area of prism 2 area of base perimeter of base height. Circle with radius of r.
If the prism is regular the bases are regular polygons. Area of the base. Usually if right or oblique is not mentioned you can assume the prism is a right prism. We can also use the formula.
Area lw 7 4 28 cm 2. And so the perimeter is ns where s is the side length and n is the number of sides. In this case the surface area formula simplifies to where. Rectangle with length l and with width w.
