# Surface Area of a triangular pyramid Calculator

Solving a **triangular **pyramid is a difficult **task** because of the **complex** structure of this** figure**. It will be **hard **for you to **understand **its sides and find different **measurements**. For **example**, you won’t be able to find the surface **area **if you don’t know about this figure **comprehensively**.

In this **regard**, the most **suitable **and appropriate **approach **to solve your **questions **is using the **surface area of a triangular pyramid calculator**. You can use this maths calculator to solve a **pyramid **with any measurements. **Read **till the end to understand what this **figure **is and how to **use **our online **calculator **for finding its **surface **area.

## What is the surface area of a triangular pyramid?

The **surface **area is a common **term **referred to the **region **covered by the **plane **sides of any **figure**/shape. In the **case **of a triangular **pyramid**, the surface **area **is the region **bounded **by its triangular **sides **and the **slant **height.

All these sides are plain **lengths** that **surround **a region. We **can **calculate the **surface **area using the **pyramid’s **triangular **base **and its slant **height **(Perpendicular height). The unit of the surface area of a **triangular pyramid** will be the **square **of the unit in which the **lengths **have been **measured**.

### How to find the surface area of a triangular pyramid?

You can **easily **find the surface area of a **triangular **pyramid using a **specific **formula. Here we have **listed **the formula that you **can **use in this regard.

Surface area of a triangular pyramid = 1/2 (a × b) + 3/2 (b × s)

In this formula:

- “a” represents the base of the triangular side.
- “b” represents the perpendicular length of the triangular side.
- “s” represents the slant height.

By putting the values in the above formula, you can easily find the measure of the surface area of a triangular pyramid. Here is a solved example to understand the procedure.

**Example 1:**

Find the surface area of a triangular pyramid if the lengths of sides are: a = 3m, b = 5m, and s = 9m.

**Solution:**

As we have all values that we need to put in the above formula, so,

As we have all values that we need to put in the above formula, so,

Surface area of a triangular pyramid = 1/2 (3 × 5) + 3/2 (5 × 9) Sq. meters

= 15/2 + 135/2 Sq. meters

By solving,

= 75 m^{2}
