Question

Write the formulas which are you learned from 5 class to 9th classes

Answer 1

vol. of cuboid = l*b
vol. of cube = l^3
(a+b) (a-b) = a^2 - b^2
(a-b)^2 = a^2 - 2ab + b^2
(a+b)^2 = a^2 + 2ab + b^2

Answer 2

Vol. Of cuboid -l*b*h
Total surface area of cube-6a square
". ". ". " cuboid-
2(lb+bh+lh)
Area of cube -side square
Area of cuboid- l*b

Perimeter of cylinder-2πr
Curved surface area- 2πrh
