1. What is the Height of Square Pyramid given Base Angle?

The height of a square pyramid is the perpendicular distance from the apex to the base of the pyramid. This calculator determines the height when given the edge length of the base, slant height, and base angle.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ h = \sqrt{\frac{l_e(Base)^2}{4} + h_{slant}^2 - (l_e(Base) \times h_{slant} \times \cos(\angle Base))} \]

Where:

\( h \) — Height of Square Pyramid (m)
\( l_e(Base) \) — Edge Length of Base of Square Pyramid (m)
\( h_{slant} \) — Slant Height of Square Pyramid (m)
\( \angle Base \) — Base Angle of Square Pyramid (rad)

Explanation: This formula combines geometric relationships and trigonometric functions to calculate the perpendicular height of the pyramid based on its base dimensions and angles.

3. Importance of Height Calculation

Details: Calculating the height of a square pyramid is essential in architecture, engineering, and geometry for determining volume, surface area, and structural properties of pyramidal structures.

4. Using the Calculator

Tips: Enter the edge length of base and slant height in meters, and base angle in radians. All values must be positive numbers with the base angle typically between 0 and π/2 radians.

5. Frequently Asked Questions (FAQ)

Q1: What is the range of valid values for base angle?
A: The base angle should typically be between 0 and π/2 radians (0-90 degrees) for a physically realizable pyramid.

Q2: Can this formula be used for other pyramid types?
A: This specific formula is designed for square pyramids. Other pyramid types (triangular, pentagonal, etc.) require different formulas.

Q3: What if I have the height and need to find another parameter?
A: The formula can be rearranged algebraically to solve for any of the other variables if the remaining parameters are known.

Q4: How accurate is this calculation?
A: The calculation is mathematically exact based on the input parameters, assuming ideal geometric conditions.

Q5: What are practical applications of this calculation?
A: This calculation is used in architectural design, construction planning, 3D modeling, and educational geometry problems involving pyramidal structures.
