A square plot of some size , at four corners equal squares of some size are cut and is formed as open box. If this open box carries 128ml of oil. What is the size of the plate i.e. side
a.17 b.14 c.13 d.none of these

• let us assume y*y is the square cut at four corners.
  
  After making open box let us assume x*x is base area and y is the height.
  
  volume=x*x*y=128
  
  so possibilities are :
  
  1)8*8*2 => initial side =8+2+2 = 12
  
  2)4*4*8 => initial side = 4+8+8 = 20
  
  3)2*2*32 => initial side =2+32+32=66
  
  so, answer is D.

• all the answers are wrong it is 12
  
  len * breadth * height must be 128
  
  len = breadth since it is a square plot..
  
  hence height = 2
  
  len = 8 + 2 + 2 = 12 cm
