CHAPTER 12 SOLID GEOMETRY 1 1. Geometric solids are three-dimensional shapes, that have length, breadth and

height. Cylinder Cube

Edge Face Vertex Cuboid

2. A cuboid and a cube each has 8 vertices, 12 edges and 6 faces. 3. A cube is a special type of cuboid in which all the edges have the same length.

4. A cube and a cuboid can be made by joining 6 faces or by folding the layouts

of the solids.

5. Volume is a measure of the amount of space occupied.

6. Volume of a cuboid = Length x Breadth x Height

7. Volume of a cube = Length x Length x Length Length

Breadth Height
