===Objectives===
===Estimated Time===
15 minutes.
===Prerequisites/Instructions, prior preparations, if any===
#Cube and its properties should have been done.
#Formula to find the area of a square.
===Materials/ Resources needed===
Laptop, geogebra file, projector and a pointer.
===Process (How to do the activity)===
#Project the geogebra file that would enable the students to visualise an opened cube.
#Ask the following questions.
*Developmental Questions:
#What is the formula to find the area of a square ?
#What does the term 'area' mean ?
#What is the meaning of total surface area ?
#How many squares are there totally in a cube ?
#Therefore what is the total surface area of a cube.?
#What does the term 'lateral' mean ?
#What is lateral surface area ?
#How many squares are there in a lateral surface of a cube ?
#Hence what is the formula to find the lateral surface area of a cube ?
#What does the term 'volume'mean ?
#What is the formula for volume in general?
#What is the formula for volume of cube ?
*Evaluation
#Were the students able to comprehend the difference between area and volume ?
#Were they able to understand the distinction between the lateral surface area and total surface area ?
*Question Corner:
#What is the formula to find the area for a cuboid cantainer with no lid and with lid ?
#Give some examples of objects which are cuboidal in shape.
