Dimensions of the metal block ,
Length = l = 2.25 m = 225 cm
Breadth = b = 150 cm
Height = h = 27 cm
Each side of the cube = a = 45 cm
If block is melted and cast into
Cubes
Let number of cubes = n
n = volume of block / volume of a cube
= ( lbh ) /a³
= ( 225 × 150 ×27 )/ ( 45 )³
= 10
Number of cubes formed = n = 10
