One iron solid is a cuboid of dimension 30cm x 30 cm x 42.6cm.It is melted and cubes each of 3 cm are mouled from it.Find the number of cubes formed.
Volume of the solid cuboid = l*b*h = 30*30*42.6 cm cube.
Volume of one melted cube = (side)3 = 3*3*3cm cube.
Number of cubes = Volume of cuboid/Volume of Cube = 30*30*42.6/3*3*3 = 1420.
Cheers!!!!!!!!!!!!!
