**Rectangular pyramid** is one of the forms of geometric shapes that have flat sides and are rectangular. The shape of a rectangular pyramid is very common in everyday life, such as geometric shapes in houses, office buildings, and so on. To calculate the surface area of a rectangular pyramid, we need certain formulas that we will discuss further in this article.

## What is the Surface Area of a Quadrilateral Pyramid?

**Surface area of a rectangular pyramid** is the total area of all sides of the rectangular pyramid. The surface area of a rectangular pyramid can be used to calculate the material requirements for making a pyramid, such as paper to make a pyramid model, paint to color the pyramid, or building materials to build a pyramid on a large scale.

## Formula for the Surface Area of a Rectangle

To calculate the surface area of a rectangular pyramid, we can use the following general formula:

**Base Area**: for a rectangular pyramid, the base area can be calculated using the formula**l = s x s**where l is the area of the base and s is the length of the side of the base of the pyramid.**Vertical Side Area**: the area of the vertical side of a rectangular pyramid can be calculated using the formula**l = p x t**where l is the area of the vertical side, p is the length of the side of the pyramid, and t is the height of the pyramid.

With the formulas above, we can calculate the total surface area of a rectangular pyramid using the formula:

**Surface Area = Base Area + Vertical Side Area**

## Sample Questions and Solutions

To further understand the use of the surface area formula for a rectangular pyramid, here is an example of a question and its solution:

**Example Questions:** A rectangular pyramid has a base side length of 6 cm and a height of 8 cm. Calculate the total surface area of the rectangular pyramid.

**Solution:**

- Luas Alas = 6 cm x 6 cm = 36 cm
^{2} - Vertical Side Area = 6 cm x 8 cm = 48 cm
^{2} - Surface Area = 36 cm
^{2}+ 48 cm^{2}= 84 cm^{2}

So, the total surface area of the rectangular pyramid is 84 cm^{2}.

## Advantages and Uses of the Surface Area Formula for a Quadrilateral Pyramid

Using the surface area formula for a rectangular pyramid has several advantages and uses, including:

**Saving time**: By calculating the surface area of a rectangular pyramid using the available formula, we can save time in the calculation process.**Making Planning Easier**: By knowing the surface area of a rectangular pyramid, we can more easily plan the use of materials and the budget required.**Minimizing Errors**: Using the surface area formula for a rectangular pyramid can help minimize calculation errors, so that the results obtained are more accurate.

## Closing

Thus the discussion of the surface area formula of a rectangular pyramid. By understanding the formula and examples of its use, it is hoped that readers can more easily calculate the surface area of a rectangular pyramid in various situations. Good luck!
