All faces of a cube with an 8 meter edge are painted red if the cube is cut in to

given 8meter edge i.e,n=8/2 =4
now,cube formula for exactly one face painted is (n-2)^2*6
(4-2)^2*6
=4*6
=24(ans)

each has 4 that are painted on exactly one face ,
cube has 6 faces so,6*4=24

4 in each face so 6*4=24

6 faces and n/2=4 thrfor 6*4=24 ans

whenever a cube is cut into smaller cubes. calculate n.

n=edge of bigger cube/edge of smaller cube.

in this case n=8/2=3

no.of 3 faces=8(always)
no.of 2 faces=(n-2)*12=12
no.of 1 faces=(n-2)^6=6
no.of 0 faces=(n-2)^3=1

4 on each face therefore total number of 6*4=24 cubes.

All faces of a cube with an 8 meter edge
are painted red .if the cube is cut in to smaller cube with a 2 meter edge ,how many of 2 meter cubes have paint on exactly one face ?
