Step-by-step explanation:
Given that -
length of cuboidal piece = 12m= 1200cm
breadth of cuboidal piece = 4m = 400cm
height of cuboidal piece = 40cm
length = breadth = height of cubical piece = 4cm
volume of cuboidal piece = l×b×h
= 1200 × 400 × 40 = 19200000 cm^3
volume of cubical piece = l^3
= 4^2 = 4×4×4= 64cm ^3
Number of pieces = 19200000/64 = 300000
