Answers
Answer:
here's is Ur answer
Step-by-step explanation:
When the painted cube is cute into 125 small equal cubes, we have:
A 3 faces painted cube on every corner
⇒Number of cubes with 3 face painted=1×8=8
Three 2-faces painted cube on every edge
⇒Number of cubes with 2 face painted=3×12=36
Nine single face painted cube on side
⇒Number of cubes with 1 face painted=9×6=54
∴ Number of cubes with no face painted=125−8−36−54=27
Answer:
96 cube have only one face painted.
Step-by-step explanation:
Disclaimer: The question is incorrect, correct question is:
A solid wooden cube is painted blue on all its faces, the cube is then cut into smaller cubes,with each edge one-sixth of the edge of the original cube. How many of the smaller cubes will have only one face obtained?
Given: A solid wooden cube Is Painted Blue on all its faces.
When the cube is cut down into smaller cubes, with an edge 1/6 th of the edge of the original cube.
= 6 * 6 * 6= 216 cubes
Now cube adjacent to the edges will have more than one face painted. Hence, the number of cubes having one face painted is = 6 * 4 * 4
= 96 cubes.
Therefore, 96 Smaller cubes will have only one face painted.
