Across
- 4. – a two-dimensional model or drawing that can be folded into a three-dimensional solid
- 7. – the measurement attribute that describes the number of square units a figure or region covers
- 10. – the length of a side that is perpendicular to both bases
- 11. – any two congruent, opposite, and parallel faces shaped like rectangles; exactly 3 possible sets
- 12. – the sum of all the surface areas of a figure; the number of square units needed to cover all of the surfaces (bases and lateral area)
- 14. – the measurement attribute of the amount of space occupied by matter
- 15. – a figure that has measurements including length, width (depth), and height
- 16. – the point (corner) where three or more edges of the three-dimensional figure meet
- 17. – a triangular face opposite the common vertex (apex) where the 3 triangular faces meet
- 18. – the two congruent, opposite and parallel faces shaped like triangles
- 19. – a three-dimensional figure containing two congruent and parallel faces that are polygons
- 20. – a three-dimensional figure containing a base that is a polygon and the faces are triangles that share a common vertex, also known as an apex
- 21. – where the sides of two faces meet on the three-dimensional figure
Down
- 1. – the set of numbers that can be expressed as a fraction , where a and b are counting (natural) numbers
- 2. – the length of a perpendicular line segment from the vertex of the pyramid to the base
- 3. – the length of a side that is perpendicular to both bases
- 5. – the sum of all the lateral surface areas of a figure; the number of square units needed to cover the lateral view (area excluding the base(s) of a three-dimensional figure)
- 6. – a rectangular face opposite the common vertex (apex) where the 4 triangular faces meet
- 8. – the length of a perpendicular line segment from the vertex of the pyramid to the base
- 9. – a flat surface of a three-dimensional figure
- 13. – of equal measure, having exactly the same size and same shape
