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. Surface area of a cylinder: A = 2πr² + 2πrh, where r is the radius and h is the height of the cylinder.

Surface Area Formula of Cube. A cube is a six-faced 3D shape in which all the faces are equal. A cube is a three-dimensional shape with several key characteristics: Formulas for the Surface Area of Cube a are given by: Lateral Surface Area (LSA) of Cube = 4a 2; Total Surface Area (TSA) of Cube = 6a 2; Where a is the Side of a Cube.

A sphere is a perfectly round 3D shape where every point on the surface is equidistant from the center. The distance is the radius, r. Surface area = 4πr 2; Volume = (4 ⁄ 3)πr 3

The following table provides a list of all mensuration formulas for 3D shapes: Shape: Volume : Curved Surface Area or Lateral Surface Area: Total Surface Area: Figure: Cube: a 3: LSA = 4 a 2: 6a 2: ... Understanding how to calculate the surface area and volume of various 3D shapes like cuboids, cubes, cylinders, and more is critical for solving ...

Examples Using Surface Area Formula Example 1: A cylindrical tank has a radius 4 yd and height 8 yd, using the surface area formula of the cylinder find its surface area. If the cost of the painting cylindrical tank is $6 per yd 2, what will be the total cost of the painting?. Solution: We know that total Surface Area formula of cylinder = Curved Surface Area of cylinder + area of the top and ...

The total area occupied by the surfaces of an object is called its surface area. In geometry, different 3D shapes have different surface areas which can be easily calculated using the formulas that we will be learning in this article.The surface area is classified into two categories: Lateral surface area or Curved surface area

The surface area of a 3D object is the total area covered by its outer surfaces. It is essential for applications such as material estimation, packaging, and design. Different shapes require different formulas to calculate their surface area.

Surface area. In geometry, the surface area of a 3D shape or geometric figure is the amount of space occupied by its surfaces. ... Substituting S = 752 and r = 4 into the formula for the surface area of a right cylinder: 752 = 2π(4) 2 + 2π(4)h. 752 = 32π + 8πh.

Formulas for Different ...

Surface area of a sphere. The surface area formula for a sphere is 4 x π x (diameter / 2) 2, where (diameter / 2) is the radius of the sphere (d = 2 x r), so another way to write it is 4 x π x radius 2.Visual on the figure below: A sphere's surface area can be calculated just by knowing its diameter, or radius (diameter = 2 x radius). π is, of course, the well-known mathematical constant ...

Surface Area of Cube. Thus, putting this in the above formula Surface area of cube = 2(a 2 + a 2 + a 2) ⇒ 2(3a 2) = 6a 2. Volume of Cube. Similar to above method, let’s substitute the length of side in the formula. Volume = lbh = aaa = a 3. Right Circular Cylinder

So the total surface area is 6 times that, or 24 square centimeters. For more, see Surface area of a cube. Shapes with curved surfaces. Although a little harder to visualize, shapes with curved surfaces have surface area too. The cylinder on the right can be thought of as two circles at each end and a strip wrapped around to form the body ...
