Understanding the geometry of a tetrahedron is a key part of learning about three-dimensional shapes. A tetrahedron is a polyhedron with four triangular faces, and its volume and surface area can be calculated using the formulas:
$ \text{Volume} , V = \frac{1}{3} \times \text{Base Area} , B \times \text{Height} , h $
$ \text{Surface Area} , S = \text{Sum of the areas of all four triangular faces} $
This Tetrahedron worksheet provides clear examples, step-by-step guidance, and exercises to practice calculating both volume and surface area. By completing this worksheet, students will strengthen their spatial reasoning, gain confidence in geometric calculations, and be well-prepared for tests involving 3D shapes.
