1. Edge is the flat surface of a solid.
2. Rectangular prisms are solid figures which have 12 edges, 8 vertices and 6 rectangular
faces.
3. A cylinder is a solid figure which has 2 faces and 2 edges.
4. A cone has a flat surface.
5.
Apyramid has triangular faces.​

Answer 1

(1) F

(2) T

(3) F

(4) T

(5) T

Explanation:

(1) False; The edge is not a flat surface but rather it is the point where two surfaces meet

(2) True; Rectangular prisms, also known as cuboids have the following properties.

`Edges = 12\\ Vertices = 8\\ Faces = 6`

(3) False; A cylinder has 3 faces (2 flat faces and 1 curved face)

(4) True; A cone has 1 flat surface

(5) True; All pyramids have triangular faces
