A cubical solid of metal has lenght,breadthand height as 40cm,30cm and 25 cm.If this solid is melted and recasted into solid cubes each of side 5 cm,find

Length = 40 cm Breadth = 30 cm Height = 25 cm Volume of the cuboidal metal solid = lbh = 40 x 30 x 25 = 30000 cm^3

Volume obtained Cubical box by melting = 6a^3 = 6 x 5 x 5 x 5 = 750 cm^3

Number of cubes obtained = Initial volume / final volume = 30000/750 Ans: = 40 Therefore number of cubes = 40. Hope this helped you. And please confirm with ur teachers or any experts here if any wrong I have done. I think the sum is correct!. :-)

It is a cuboid with dimension length = 40 cm breadth = 30 cm height = 25 cm Volume(V)= lbh = 40×30×25 = 30000 cm³

Dimension of small cube obtained after recast is 5cm volume(v) = a³ = 5³ = 125 cm³

Number of cubes= V/v = 30000/125 = 240 So total 240 cubes can be obtained.
