These equations will give you correct answers if you keep the units straight. For example - to find the surface area of a cube with sides of 5 inches, the equation is: Surface Area = 6*(5 inches) 2 = 6*(25 square inches) = 150 sq. inches
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.
Here we will learn how to calculate the surface area of a variety of three-dimensional shapes, including cuboids, prisms, cylinders, cones and spheres. There are also surface area worksheets based on Edexcel, AQA and OCR exam questions, along with further guidance on where to go next if you’re still stuck.
The total surface area of a cylinder is given as the sum of lateral surface area and the area of two bases. It is mathematically expressed as 2πr(r + h) and is expressed in square units, like m 2 , in 2 , cm 2 , yd 2 , etc.

Use this surface area calculator to easily calculate the surface area of common 3-dimensional bodies like a cube, rectangular box, cylinder, sphere, cone, and triangular prism. Total surface area formulas and explanation below.
The total surface area formula of cube = 6a 2 where "a" is the side length. The lateral surface area formula of a cube is the sum of areas of all lateral side faces of the cube. LSA = 4a 2 where "a" is the side length.
