the whole surface of a rectangular block is 8788 square cm.if the length ,breadth and heights are in the ratio of 4:3:2,find length

• length=4x ,breadth=3x, height=2x
  surface area=2(lb+bh+hl)
  ->2(12x^2+6x^2+8x^2)=8788
  ->26x^2=4394
  so, x=13
  so, length=4*13=52cm

• l= 4x , b=3x ,h=2x
  surface area = 2(lb+bh+lh)
  2(4x*3x+3x*2x+4x*2x)=8788
  52x^2=8788
  x=13 then ans is 13*4=52 cm

• l=4x b=3x h=2x
  area=2(4x*3x+3x*2x+2x*4x)=8788
  52x^2=8788 => x=13
  then l=4*13=52cm

• 52cm
  
  whole surface area of a rectangle=2(lb+bh+lh)
  here l=4x, b=3x, h=2x
  from above equ 2(26x^2)=8788
  x=13
  thus l=13*4=52

• 4x+3x+2x=8788
  
  9x=8788
  
  x=976.444
  
  l=4*976.44=3905.78
  b=3*976.44=2929.33
  h=2*976.44=1952.88
