**Allcalculator.net **offers a convenient and efficient way to calculate the surface area of various common shapes. By utilizing our reliable **Surface area calculation **tool, you can quickly obtain accurate values for shapes such as squares, circles, triangles, and more. Whether you're working on a school project or need precise measurements for construction purposes, our user-friendly calculator will assist you in obtaining the desired results with ease.

**What do you mean by surface area?**

The **Surface Area** is the total area that the surface occupies the object. It is the total area of the surface of a 3D object. The surface area has split into two types which is

- Base area
- Lateral surface

The lateral surface is the area of an object's sides, excluding its base and top. The division is used for shapes with an obvious distinction between the base and the other part.

E.g.:

- Cone
- Pyramid
- Cylinder
- Triangular prism

It is rarely applied to solids for which you are unsure which should be treated as bases, and don't use it for smooth surfaces such as spheres.

**How can you use the surface area calculator?**

The Surface Area Calculator is so handy and comfortable to use. You can check your answer to perform the calculation for you.

- First, choose the shape from the drop-down menu.
- Enter the value of the length and choose the unit of measurement from the drop-down menu.
- The calculator generates the value of the surface area along with an illustration of the shape you have chosen.

**How will you find out the surface area of a cylinder?**

To determine a cylinder's Surface Area, you have to know two values: the radius of a base and the height of the cylinder. The equation to find the surface area of a cylinder is as follows:

This formula, in case a circle is a base:

A = 2πr2 + 2πrh

This formula for a cylinder as a base:

A = A (lateral) + 2 A(base)

If one side length is a cylinder height and the second one is the unfolded circle circumference:

A(base) = π x r2

A(lateral) = h x (2 x π x r)
