WebSep 24, 2024 · Surface area the given polyhedron is equals to 84square units.. What is surface area? "Surface area is the total area of all the surfaces occupied by any three dimensional body." Formula used. Area of right angled triangle = ( 1/2) × base ×height. Area of rectangle = length ×width. According to the question, WebThe surface area of a sphere is equal to 4Π times the square of the radius of the sphere: 4Πr2. This formula can be derived by thinkin g of the sphere as a polyhedron consisting entirely of pyramids sharing the center of the sphere as their vertex. As the area of the base of such pyramids decreases, the surface more closely resembles a sphere.
