Pyramid Frustum Calculator

A pyramid frustum is created by cutting a pyramid with a plane parallel to its base. It has two parallel square bases of different sizes connected by trapezoidal faces.

Key Properties:

• 6 faces: 2 square bases + 4 trapezoidal lateral faces
• 12 edges: 4 top + 4 bottom + 4 connecting edges
• 8 vertices: 4 top + 4 bottom
• When a₁ = 0, it becomes a complete pyramid
• When a₁ = a₂, it becomes a prism
