How many iron rods, each of length 7 m and diameter 2 cm can be made out of 0.88 cubic metre of iron. A. 400
Feedback Volume of 1 rod = (22/7 x 1/100 x 1/100 x 7) = 11/5000 cu.cm
Volume of iron = 0.88 cu. m
Number of Rods = (0.88 x 5000/11) = 400
Volume of iron = 0.88 cu. m
Number of Rods = (0.88 x 5000/11) = 400
B. 800
