Surface Area Formulas. In general, the surface area is the sum of all the areas of all the shapes that cover the surface of the object. Cube | Rectangular Prism | Prism | Sphere | Cylinder | Units. Note: "ab" means "a" multiplied by "b". "a 2 " means "a squared", which is the same as "a" times "a". Be careful!! Units count.
Mar 18, 2024 · Our surface area calculator can find the surface area of seven different solids. The formula depends on the type of solid. Surface area of a sphere: A = 4πr², where r stands for the radius of the sphere. Surface area of a cube: A = 6a², where a is the side length.
The surface area of a rectangular prism can be calculated by using the following formula: Surface area of rectangular prism = 2(lw + wh + lh), where l, w, and h are the length, width, and height of the rectangular prism respectively.
Surface area formulas in geometry refer to the lateral surface and total surface areas of different geometrical objects. To recall, the surface area of an object is the total area of the outside surfaces of the three-dimensional object i.e, the total sum of the area of the faces of the object.
The surface area formula is used to calculate the total area occupied by the surfaces of an object. The surface area formula is classified into two categories as curved surface area formula or Lateral surface area formula and the total surface area formula.
A table of surface area formulas and volume formulas used to calculate the surface area and volume of three-dimensional geometrical shapes: cube, cuboid, prism, solid cylinder, hollow cylinder, cone, pyramid, sphere and hemisphere. A more detailed explanation (in text and video) of each surface area formula. Related Pages.
The total surface area of the cylinder formula is the sum of the base surface area and the lateral surface area: total_area = base_area + lateral_area , or total_area = 2 * π * r² + (2 * π * r) * h , or total_area = 2 * π * r * (r + h) .
