One iron solid is a cuboid of dimension 30cm x 30 cm x 42.6cm.It is melted and cubes each of 3 cm are mouled from it.Find the number of cubes formed.
dimensions of the cuboid :-
- length = 30cm
- breadth = 30cm
- height = 42.6cm
dimensions of the cube :-
- side = 3cm
ATQ, the solid cuboid of the given dimensions is melted and converted into small cubes of side 3cm.
we've to find the no. of cubes formed.
for that we needa divided the volume of cuboid by the volume of the cube.
hence, the no.s of cube formed = (30 × 30 × 42.5)/(3 × 3 × 3)
= (10 × 10 × 42.5)/3
= 1416.6 approximately
hence, 1416 full cubes can be formed from the cuboid.
