we need to carve out 125 identical cubes from a cube . what is the minimum number of cuts needed?
Read Solution (Total 12)
-
- Total no. of cubes=n^3
here n^3 =125 which makes n=5,
also minimum no. of cuts required =3(n-1)
hence, 3(5-1)=12 cuts. - 9 years agoHelpfull: Yes(23) No(1)
- 12 cuts
4 cuts from first side + 4 cuts from second side + 4 cuts from the first side - 9 years agoHelpfull: Yes(7) No(1)
- as Cube has 3 dimensions i.e L,B,H
now 1 cut on any side divide cube into 2 parts
similarly 4 cuts on any side ( say on L) will divide it in 5 Parts
Hence 4 cuts on B will make ( 5*5 =25 parts ) and 4 cuts on H ( 5*5*5 = 125 )
Therefore
4+4+4 =12 cuts required

- 4 cuts from each side
5×5×5=125
5 (1×1×1) 5 parts from each side - 9 years agoHelpfull: Yes(1) No(3)
- 12 cuts needed from 3 faces of cube l,b,h.
ans is 12 - 9 years agoHelpfull: Yes(1) No(0)

- 5^3=125 SO 3 CUTS NEEDED
- 9 years agoHelpfull: Yes(0) No(9)
- 12=4+4+4
cut - 9 years agoHelpfull: Yes(0) No(2)
- totally 16 cuts are needed
