A pyramid with an equilateral triangular base is a three-dimensional shape that has a base made up of an equilateral triangle and four congruent triangular faces that meet at a common vertex. To calculate the surface area of a pyramid with an equilateral triangular base, you need to add the area of the base to the area of each of the triangular faces.

The surface area of a pyramid with an equilateral triangular base can be used in many applications. For example, architects use this concept when designing the structure of a building. They can use the surface area of a pyramid to calculate the amount of materials needed to build the structure. Engineers can use the surface area of a pyramid to determine the amount of stress a structure can withstand before collapsing. The surface area of a pyramid can also be used in physics to calculate the amount of force needed to push or pull an object in a certain direction.

In addition, the surface area of a pyramid with an equilateral triangular base has unique properties that make it ideal for use in various scientific applications. For instance, scientists can use this concept to understand the relationship between surface area and volume, which is crucial in many fields of science, including biology and chemistry. Furthermore, the surface area of a pyramid with an equilateral triangular base can be used to calculate the amount of pressure exerted by a fluid on an object placed in it, which is useful in fields like hydrology and geology.

Overall, the surface area of a pyramid with an equilateral triangular base is an important concept in mathematics, physics, and science, and has various real-life applications. Whether you are an architect, engineer, scientist or a student learning about geometry, understanding the surface area of a pyramid can help you solve complex problems and design structures that are both functional and efficient.

The formula for determining the surface area of a pyramid with an equilateral triangular base is defined as:
$$SA$$ $$=$$ $$\dfrac{a}{2}$$ $$\cdot$$ $$\Big(\sqrt{a^2 - (\dfrac{a}{2})^2}$$ $$+$$ $$3$$ $$\cdot$$ $$h_s\Big)$$
$$SA$$: the surface area of the pyramid
$$a$$: the length of any side of the base triangle
$$h_s$$: the length of the slant height
The SI unit of surface area is: $$square \text{ } meter\text{ }(m^2)$$

## Find $$SA$$
