Question

question 1 of 10 using the piling method, which of the following can be constructed from polygons alone or discs alone? check all that apply. a. pyramid (including the vertex) b. prism c. cylinder d. cone (not including the vertex) e. cube f. cone (including the vertex)

Explanation:

Answer:

B. Prism
C. Cylinder
E. Cube

(Note: A prism can be constructed by piling polygons (the bases) along the height, a cylinder by piling discs, and a cube is a type of prism with square bases, so also constructed from polygons. A pyramid (A) has a vertex with decreasing cross - sections, a cone (including vertex F) has a vertex with decreasing circular cross - sections, and a cone not including vertex D still has a non - constant cross - section that can't be just discs or polygons in a piling sense as the radius changes, while prism, cylinder, cube have constant cross - sections (polygons for prism and cube, discs for cylinder) when piled.)
