Introduction

When it comes to calculating the surface area of a square pyramid, there are several formulas and techniques that can be used. In this article, we will explore the process of finding the surface area of a square pyramid with a base of 4 inches and a height of 3 inches. We will also discuss the importance of understanding the properties of a square pyramid and how to apply mathematical formulas to solve real-world problems.

Understanding the Properties of a Square Pyramid

A square pyramid is a three-dimensional shape with a square base and four triangular faces that meet at the apex. The base of the pyramid is a square with equal sides, and the height of the pyramid is the distance from the center of the base to the apex. The surface area of a square pyramid is the total area of all its faces, including the base and the four triangular faces.

Formula for the Surface Area of a Square Pyramid

The formula for the surface area of a square pyramid is:

SA = B + 4 × (1/2) × b × s

Where:

SA is the surface area of the pyramid
B is the area of the base
b is the length of the base
s is the slant height of the pyramid

Calculating the Slant Height of the Pyramid

To calculate the slant height of the pyramid, we need to use the Pythagorean theorem. The slant height is the hypotenuse of a right triangle formed by the height of the pyramid and half the length of the base.

Pythagorean Theorem

The Pythagorean theorem states that:

a² + b² = c²

Where:

a is the height of the pyramid
b is half the length of the base
c is the slant height of the pyramid

Calculating the Slant Height of the Pyramid with a Base of 4 Inches and a Height of 3 Inches

Using the Pythagorean theorem, we can calculate the slant height of the pyramid as follows:

a = 3 inches (height of the pyramid) b = 2 inches (half the length of the base) c = √(a² + b²) c = √(3² + 2²) c = √(9 + 4) c = √13 c ≈ 3.61 inches

Calculating the Surface Area of the Pyramid

Now that we have the slant height of the pyramid, we can calculate the surface area using the formula:

SA = B + 4 × (1/2) × b × s

Where:

SA is the surface area of the pyramid
B is the area of the base
b is the length of the base
s is the slant height of the pyramid

Calculating the Area of the Base

The area of the base is:

B = b² B = 4² B = 16 square inches

Calculating the Surface Area of the Pyramid

Now we can calculate the surface area of the pyramid as follows:

SA = B + 4 × (1/2) × b × s SA = 16 + 4 × (1/2) × 4 × 3.61 SA = 16 + 4 × 2 × 3.61 SA = 16 + 28.96 SA ≈ 44.96 square inches

In this article, we have explored the process of finding the surface area of a square pyramid with a base of 4 inches and a height of 3 inches. We have discussed the importance of understanding the properties of a square pyramid and how to apply mathematical formulas to solve real-world problems. We have also calculated the slant height of the pyramid using the Pythagorean theorem and used it to calculate the surface area of the pyramid.
