Answer:
21 cm
Step-by-step explanation:
volume of cuboid=44×21×12=11088 cm³
volume of cone = ⅓×πr²h
then,
=> 11088=⅓×22/7×r²×24
=> (11088×3×7)/22×24 = r²
=> 232848/528 = r²
=> 441 = r²
=> r = √441
=> r = 21 cm

Answer:
The dimensions of the cuboid are 44 cm, 21 cm and 12 cm. Let the radius of the cone be r cm. It is given that cuboid is melted to form a cone. Thus, the radius of the base of cone is 21 cm
