How To Calculate Surface Area Gcse Maths Steps Examples 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. surface area of a cylinder:a = 2πr² 2πrh, where r is the radius and h is the height of the cylinder. surface area of a cone:a = πr² πr√ (r² h². Surface area calculator: this user friendly calculator not only gives the accurate result, but also provides the formulas, step by step procedure to solve the surface area, definition. the only thing you need to do is choose the shape and enter required input fields, press on the calculate button to get the result.
Surface Area Formulas For All 3d Shapes Surface area of a box. the surface area formula for a rectangular box is 2 x (height x width width x length height x length), as seen in the figure below:. since a rectangular box or tank has opposite sides which are equal, we calculate each unique side's area, then add them up together, and finally multiply by two to find the total surface area. The surface area of a closed cylinder can be calculated by summing the total areas of its base and lateral surface: base sa = 2πr 2. lateral sa = 2πrh. total sa = 2πr (r h) where r is the radius and h is the height. jeremy has a large cylindrical fish tank that he bathes in because he doesn't like showers or bathtubs. Surface area and volume are calculated for any three dimensional geometrical shape. the surface area of any given object is the area or region occupied by the surface of the object. whereas volume is the amount of space available in an object. in geometry, there are different shapes and sizes such as sphere, cube, cuboid, cone, cylinder, etc. Calculator online for a the surface area of a capsule, cone, conical frustum, cube, cylinder, hemisphere, square pyramid, rectangular prism, triangular prism, sphere, or spherical cap. calculate the unknown defining side lengths, circumferences, volumes or radii of a various geometric shapes with any 2 known variables. online calculators and formulas for a surface area and other geometry problems.
