Answer:
315cm or 3.15m
Step-by-step explanation:
volume of rectangular solid- 60 cm by 66cm by 10 cm.
radius of the cylindrical wire- 2cm
volume of the rectangular solid = volume of the cylindrical wire( as it is melted so the volume will remain unchanged)
volume of a cylinder= πr²h
let the length/height be l
l=60×66×10×7/22×2×2
=15×3×7
315cm or 3.15m
