A rectangular plate with length 8 inches, breadth 11 inches and thickness 2 inches is available. What is the length of the circular rod with diameter 10 inches and equal to the volume of the rectangular plate?

• 2.24 inches
  Volume of rectangular plate=8*11*2=176 sq.inch
  Volume of the rod(cylinder)with r=5 & length=h is given by Pi*(r^2)*h=176
  (22/7)*(5^2)*h=176, h=176*7/(22*25)=1232/550= 2.24

• Volume of rectangular plate is = l*b*h =8*11*2 = 176
  Volume of circular rod is = pie*(radius^2)*h
  Now According To Question:
  Rectangular plate volume =Volume of circular rod
  176= (22/7)*(5^2)*h (Radius = Diameter/2)
  h= 2.24 inches

• since we know that vol. of rectangle = L*B*H and vol. of circular rod = 2*3.14*r
  so L*B*H=2*3.14*R
  8*11*2=2*3.14*5*L ------(1)
  from eqn. (1)
  L=5.60inch.
