a cubical wooden block 30 cm on an edge, has all its faces painted red.if the block is cut up into smaller cubes each measuring 10 cms on an edge and each 1000 cubic cms in volume . how many such smaller cubes will have only one face painted red.

- 6 cubes will have one face painted.
from the cube, 27 small cubes are formed and from each face only the middle cube will have one face painted.
hence, answer=1 - 9 years agoHelpfull: Yes(2) No(4)
- 6.. 1 from each side...
- 9 years agoHelpfull: Yes(2) No(1)
- No of faces= 6
1 face story = (x-2)^2
6(3-2)^2=6 - 9 years agoHelpfull: Yes(2) No(0)
- 27000/1000 =27 cubes
3x3x3=27
1 face paintd is =(n-2)^2 *6 =6 - 9 years agoHelpfull: Yes(2) No(1)
- 6 face---6(n-2)^2 n=3 therefore our answer will be 6

- may be 4
in the cube in the middle part there will be only one face painted

- I think the answer is 36 .
Since side of the bigger cude is 30cm and smaller is 10 , hence each side can fit 6 small cube . Now cube has 6 faces and here all are painted red .
Small cube with color on single side = 6 * 6 - 9 years agoHelpfull: Yes(0) No(0)
- i thing if i ll cut 1000 cubic cms in volumn and its edge = 10 cm then
in one face 9 part will created and there are 6 faces so
9*6=54
so 54 can be ans - 9 years agoHelpfull: Yes(0) No(3)
- answer = 6, because every side of large cube have 1 face red paint small cube.
- 9 years agoHelpfull: Yes(0) No(0)
- middle cube of all phase with size 10*10*10 has only one red phase, so no. of phase =no. of cube having only one red phase
- 9 years agoHelpfull: Yes(0) No(1)
