If the length, breadth and the height of a cuboid are in the ratio 6:5:4 and if the total surface area is 33300 cm2cm2, then the length , breadth and height in cms, are respectively.  Choose the correct choice.
A) 90,85,60  B) 85,75,60  C) 90,75,70  D) 90,75,60  E) none
Explanation:   Let length = 6x, breadth = 5x and height =4x in cm   2(6x×5x+5x×4x+6x×4x)=33300   148x2=33300⇒x2=33300/148=
