5. SURFACE AREA
Area of square 1 = a x a
Area of square 2 = a x a
Area of square 3 = a x a
Area of square 4 = a x a
Area of square 5 = a x a
Area of square 6 = a x a
Surface Area = Area of all 6 faces
= 6a2

7. Circumference of a circle = 2πr
Area covered by a circle = (2πr) x (h)
= 2πrh

14. If we make a cone having radius and height
equal to the radius of sphere. Then a water
filled cone can fill the sphere in 4 times.
