1.	drawn out into a wire of diaellllIA solid cube of metal each of whose sides measures 2.2 cm is melted to form a cylindricalwire of radius 1 mm. Find the length of the wire so obtained.ho dud out to sink a well which is 20 m deep and has
Answer» Length of the edgebe 2.2 cm=aVolume of the cube=a³=(2.2)³=10.648cm³ Volume of the wire=πr²hRadius = 1 mm = 0.1 cm volume of cube = volume of wire height=volume/πr²=10.648×7/22×0.1×0.1=338.8cm

Answer»

Length of the edgebe 2.2 cm=aVolume of the cube=a³=(2.2)³=10.648cm³

Volume of the wire=πr²hRadius = 1 mm = 0.1 cm

volume of cube = volume of wire

height=volume/πr²=10.648×7/22×0.1×0.1=338.8cm
