Volume of each rod = Pi * r * r * l
r = 2cm/2 i.e. 1cm or .01 m
l = 7
So volume of rod = (22/7) * .01 *.01 * 7 = .0022 cubic m
Metal volume = .88
Number of possible rod = .88/.0022 = 400
Answer: 400 rods are possible
40000....because 0.88 m cube=880000 cm cube, hence number of rods = 880000/22=40000 since vol of one rod= pi*4*7/4=22 cm cube
