Question

1. The adjoining net is made up of two equilateral triangles and three
rectangles.
(i) Name the solid it represents.
(ii) How many faces, edges and vertices does this solid have?
​

Answer 1

Answer:

1). polyhedron

2). 3d shape has 8 faces 12 edges and 6 vertices

Step-by-step explanation:

A solid is a polyhedron if it is made up of only polygonal faces, the We have 4 congruent equilateral triangles.

Answer 2

i) The solid being represented is a polyhedron.

• A polyhedron (plural polyhedron) is a three-dimensional solid with flat polygonal faces, straight edges and sharp corners or vertices.
• Polyhedrons are flat solids. If all its sides are flat, every 3-dimensional solid is a polyhedron. Soccer balls, prisms, tiles, houses and pyramids are examples of real-world polyhedrons as all of these kinds have flat sides.
• Polyhedral solids have a volume associated with them, which determines how much space they occupy. Simple solid families may have simple formulas for their volumes; for instance, pyramid volumes, prisms, can be easily expressed in terms of their edge lengths or other coordinates.

ii) The said 3D shape has eight faces twelve edges and  six vertices.
