===========================================================
Introduction
In geometry, a right square pyramid is a three-dimensional shape with a square base and four triangular faces that meet at the apex. Given the altitude of the pyramid and the length of each side of the base, we can calculate the distance from the top of the pyramid to each vertex of the base. In this article, we will explore the mathematical concepts and formulas required to solve this problem.
Understanding the Geometry of a Right Square Pyramid
A right square pyramid has a square base with four equal sides, and four triangular faces that meet at the apex. The altitude of the pyramid is the distance from the center of the base to the apex. In this case, the altitude is given as 10 units, and each side of the base is given as 6 units.
Visualizing the Pyramid
To visualize the pyramid, imagine a square base with each side measuring 6 units. The altitude of the pyramid is 10 units, which means that the distance from the center of the base to the apex is 10 units.
Calculating the Distance from the Top to Each Vertex of the Base
To calculate the distance from the top of the pyramid to each vertex of the base, we need to use the Pythagorean theorem. The Pythagorean theorem states that in a right-angled triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides.
Applying the Pythagorean Theorem
Let's consider one of the triangular faces of the pyramid. The distance from the top of the pyramid to the vertex of the base is the hypotenuse of the right-angled triangle. The other two sides of the triangle are the altitude of the pyramid (10 units) and half the length of the base (3 units).
Using the Pythagorean theorem, we can calculate the distance from the top of the pyramid to each vertex of the base as follows:
- Distance from the top to each vertex of the base = √(altitude² + (half the length of the base)²)
- Distance from the top to each vertex of the base = √(10² + 3²)
- Distance from the top to each vertex of the base = √(100 + 9)
- Distance from the top to each vertex of the base = √109
Rounding the Answer to the Nearest Tenth of a Centimeter
The distance from the top of the pyramid to each vertex of the base is approximately 10.4 centimeters (rounded to the nearest tenth of a centimeter).
Conclusion
In conclusion, we have calculated the distance from the top of a right square pyramid to each vertex of the base using the Pythagorean theorem. The distance from the top to each vertex of the base is approximately 10.4 centimeters (rounded to the nearest tenth of a centimeter).
