Introduction
Cube is a special case of cuboid where l = b = h
Pre-Requisites:
About different solids- namely Cube, Cuboid & Cylinder and their importance
Activity:
Take a hollow cubical container. These are pretty often used for testing strength of cement cubes. Find the total volume of the cube. Pour water in it & see how much volume of water it is taking. Is this volume the same as total volume of the cube?
Real Life Question:
How many liters of water will fit in that cubical flask?
Key Words / FlashCards
| Key Words | Definitions (pref. in our own words) |
|---|---|
| Cube | A 3D object which has all the 3 sides to be equal |
Learning aids / Gadgets
| Gadgets | How it can be used |
|---|---|
| Carton box | Fill this with smaller cubes up to the brim. Make sure they are of the same size. Measure volumes of the individual cubes. Sum them up. Find volume of the carton box. Now, compare them. They should be equal |
Real life uses :
Cubical structures are more of day to day requirements than in large scale applications. Some water filtering tanks may be cubical solids (although most of the times, they are cuboidal) . In such a case, one will need to measure its volume
Places to visit :
Construction site, Super Markets, Grocery stores
Practical examples around us
| Examples | Explainations |
|---|---|
| Row house | Most row houses are cube shaped once you exclude the roof |
What you learn in Theory:
Volume of the Cube = Area of base x height = l x l x l
What you learn in Practice:
Cubical volume measurement represents how much quantity of anything it can accommodate within itself. You can see general examples like containers, tanks, Rubik’s cube etc.
