Across
- 3. made up of simple geometric shapes
- 4. found by finding the surface area of the sides of the object.
- 8. a polyhedron formed by connecting a polygonal base and a point, called the apex. Each base edge and apex form a triangle, called a lateral face.
- 10. a prism in which the bases are parallel, but one is not directly over the other, and all lateral faces are parallelograms.
- 11. a solid or hollow object which tapers from a circular or roughly circular base to a point.
- 14. if 2 figures have the same height and the same cross-sectional area at every point along that height, they have the same volume.
- 15. Formula: A=a2. Since all the sides are equal, the area would be length times width, which is equal to side × side.
- 17. a geometrical object that is a three-dimensional analogue to a two-dimensional circle.
- 18. having or appearing to have length, breadth, and depth.
Down
- 1. Formula: A=1/2bh. where b is the length of the base of the shape, and h is the height/altitude of the shape.
- 2. the distance measured along a lateral face from the base to the apex along the "center" of the face.
- 5. a geometric setting in which two values are required to determine the position of an element.
- 6. In geometry, the area enclosed by a shape has a radius. r is πr², Formula: A=πr2
- 7. Formula: C=2πr
- 8. n-sided polygon base, a second base which is a translated copy. all parallelograms
- 9. V=Bh , where B is the base area and h is the height.
- 12. has traditionally been a three-dimensional solid, one of the most basic of curvilinear geometric shapes. Geometrically, it can be considered as a prism with a circle as its base.
- 13. Formula: a=(a+b/2)h.The area is half its height multiplied by the sum of its two bases.
- 16. scalar quantity expressing the amount of three-dimensional space enclosed by a closed surface.
