ONE RECTANGULAR PLATE WITH LENGTH 8INCHES,BREADTH 11 INCHES AND 2 INCHES THICKNESS IS THERE. WHAT IS THE LENGTH OF THE CIRCULAR ROD WITH DIAMETER 18 INCHES AND EQUAL TO VOLUME OF RECTANGULAR PLATE?

• volume of plate = 8*11*2= 176 cubic inches
  
  volume of plate (l*b*h*) will be = volume of rod (pi*r*r*h)
  Length of rod (h) = 176/(pi*r*r) = 176/ (pi*9*9) = .69 inch

• volume of plate = 8*11*2= 176 cubic inches
  
  Area of cross section of rod of dia 18 inches = pi*9*9
  
  Length of rod = (176*7)/( 81*22) = 56/81 inches

• vol of rec plate = vol of circular rod
  8*11*2 = pi*(18sq/4)*L
  SO.L=0.69 inch

• ans:56/81
  l=176/(pie*(18/2)*(18/2))

• i think the will be
  height=(176*7)/22*7*7=8/7 inch
  
  radius=(9-2)=7 inch
