Question

An iron cube of side 1metre is cut into smaller cubes of side 10 cm each which are then stacked one over the other to form a column. The height of the column so obtained is

Answer 1

Side of iron cube = 1m

We know that
1m = 100cm

No. of small cube = volume of big
cube/volume of small cube
= 100×100×100/10×10×10
= 1000
So,
Height = 10 × 1000
= 10000cm
