1. What is the formula for the surface area of a square pyramid?

The formula to calculate the surface area of a square pyramid is:

SA = a^2 + 2a\sqrt{\frac{a^2}{4}+h^2}

or, on simplifying:

SA = a^2 + a\sqrt{{a^2}+4h^2}

, where:

SA is the surface area of the square pyramid;
a is the length of the base edge; and
h is the height of the square pyramid.

2. How to find the lateral area of a square pyramid

First of all, let's explain what the lateral area of a square pyramid is. The lateral surface area or lateral area of a square pyramid is the total area of its 4 triangular faces. We calculate the lateral area as:

LSA = {a}\sqrt{{a^2}+4h^2}

💡 The total surface area of a three-dimensional object is the sum of the base area and the lateral surface area!

SA = BA + LSA

3. How do I find the face area of a square pyramid?

The face area of a square pyramid is the area of one of its four triangular faces. We calculate the area of a triangular face, the face area (FA), using the formula:

FA = \frac{a}{2} \sqrt{\frac{a^2}{4}+h^2}

💡 The lateral surface area is the sum of the areas of four triangular faces:

LSA = 4 × FA

4. How to find the surface area of a square pyramid using slant height

To find the surface area using the slant height, we use the formula:

SA = a² + 2×a×l

🔎 Proof: The surface area of a square pyramid is the sum of the areas of its square base and four triangular faces:

SA = BA + (4 × FA)

The area of a triangle is half of the product of its base length (a) and height (l):

FA = a×l/2

Therefore, the area of four triangular faces or the lateral surface area of the square pyramid is:

4 × FA = 2 × a × l

Thus, the lateral surface area (LSA) of the square pyramid of slant height l is

LSA = 2 × a × l

and the total surface area is

SA = a² + 2 × a × l

5. How to use the surface area of a square pyramid calculator

❓ The Pyramid of Giza has a height of 480 feet. If the length of each side of the base is approximately 756 feet, what is its total surface area?

Okay, let's see how to use this total surface area of a square pyramid calculator to solve the problem given above:

Identify the measurements:
- Height (h) = 480 ft
- Base edge (a) = 756 ft
Switch the units from cm to ft and cm² to ft² (or the desired units for the area) using the drop-down list near each variable in the square-based pyramid surface area calculator.
Enter the values for height (480 ft) and base edge (756 ft).
Ta-da! You got the results in no time! Our tool uses the surface area square pyramid formula to find:
- Slant height (l) = 611 ft
- Total surface area (SA) = 1,495,322 ft²
- Base area (BA) = 571,536 ft²
- Lateral surface area (LSA) = 923,786 ft²
- Face area (FA) = 230,947 ft²
