Question

a cuboidal piece of dimensions 12m, 4m,40cm was melted into cubical Iron piece of side 4 cm each. how many pieces were made

Answer 1

Volume of cuboid ÷ Volume of cube

1200 x 400x40 ÷ 4x4x4
=300000

Answer 2

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
