Question

66 cubic centimeters of silver is drawn into a cuboid with square base of side 1 mm. find the length of the wire in metres​

Answer 1

Answer:

Step-by-step explanation:

v=66 cm³

r= 1/2 mm=.05 cm

wire is a cylinder

v= πr²h

66= 22/7*0.05²*h

66*7=22*0.05*0.05*h

462 =0.55*h

h=462/0.55=840

h= 8.4 m
