Surface area and volume of a cube

Cube is introduced and analysed to calculate the surface area.

Objectives
Understand surface area of a cube

Understand volume of a cube

Estimated Time
15 minutes.

Prerequisites/Instructions, prior preparations, if any

 * 1) Cube and its properties should have been done.
 * 2) Formula to find the area of a square.

Materials/ Resources needed
Laptop, geogebra file, projector and a pointer.

Geogebra file: Cube, Surface area of a cube

Process (How to do the activity)

 * 1) Project the geogebra file that would enable the students to visualise an opened cube.
 * 2) Ask the following questions.
 * Developmental Questions:
 * 1) What is the formula to find the area of a square ?
 * 2) What does the term 'area' mean ?
 * 3) What is the meaning of total surface area ?
 * 4) How many squares are there totally in a cube ?
 * 5) Therefore what is the total surface area of a cube.?
 * 6) What does the term 'lateral' mean ?
 * 7) What is lateral surface area ?
 * 8) How many squares are there in a lateral surface of a cube ?
 * 9) Hence what is the formula to find the lateral surface area of a cube ?
 * 10) What does the term 'volume'mean ?
 * 11) What is the formula for volume in general?
 * 12) What is the formula for volume of cube ?
 * Evaluation
 * 1) Were the students able to comprehend the difference between area and volume ?
 * 2) Were they able to understand the distinction between the lateral surface area and total surface area ?
 * Question Corner:
 * 1) What is the formula to find the area for a cuboid cantainer with no lid and with lid ?
 * 2) Give some examples of objects which are cuboidal in shape.
