1. a polyhedron is a

a) 2-dimensional shape
b) 4-dimensional shape
c) 3-dimensional shape

1. what is the difference in prism and pyramids ?

a) prism has triangular faces and pyramid has one base.
b) none of the above
c) prism has rectangular lateral faces and pyramid has triangular lateral faces.
d) prism has two congruent bases and pyramid has no base.

Explanation:

For question 9: A polyhedron is a solid figure with flat polygonal faces, edges, and vertices, which is a 3-dimensional object.
For question 10: Analyze each option:

• Option a is incorrect because prisms do not have only triangular faces (e.g., a rectangular prism has rectangular faces).
• Option d is incorrect because pyramids have one base, not no base.
• Option c is incorrect because not all prisms have rectangular lateral faces (e.g., a triangular prism has triangular bases and rectangular lateral faces, but a pentagonal prism has pentagonal bases and rectangular lateral faces; however, some prisms like oblique prisms have non-rectangular lateral faces, and pyramids have triangular lateral faces but the option's description is not universally accurate for all prisms). Thus, none of the provided options a, c, d are correct.

Answer:

1. c) 3-dimensional shape
2. b) None of the above
