Q. A box is made in form of a cube. If a second cubical box has inside dimensions three times those of the first box, how many times as much does the second box contain?

Option
A) 3
B) 6
C) 9
D) 12

• let original cube has side=x
  volume=x^3
  when dimensions are 3 times then side is 3x
  vol=(3x)^3= 27x^3
  
  so, 27x^3/x^3= 27 (I DONT KNW ABOUT THE OPTIONS PROVIDED)

• Let the side of cube be a:
  First box's surface area=6a^2
  Second Box's surface area=6(3a)^2=6*9a^2=54a^2
  i.e second/first=54a^2/6a^2=9

• If the side of first cube = x
  so volume= x^3
  
  So the side of second cube= 3x
  so volume= (3x)^3 = 27 (x^3)
  
  Second box can contain upto 27 (x^3)/x^3 = 27 times.

• Let the side of cube be x:
  surface area of first box=6a^2
  surface area of second box =6(3x)^2=54a^2
  ans=54x^2/6a^2=9
