Question

A rectangular solid metallic cuboid 9 CM ×8cm ×2cm is melted and recast into solid cubes each of Side 2 centimetre how many solid cubes can be made ?

Answer 1

Volume of CUBOID = 9×8×2 = 144cm³
Edge of Cube = 2cm
Volume of Cube = a³ = (2)³ = 8cm³
Numbers of cubes formed by melting the CUBOID = Volume of CUBOID/Volume of each cube = 144/8 = 18
Hence ,
18 cube's can by formed by melting the CUBOID
