a cube has an edge length of 12cm faces of large cube are painted how many are painted on 3,2,1 and how many are unpainted
This makes absolutely no sense to me. Sorry.
No worries! I'll try my best to help you understand. So we have a large cube with an edge length of 12cm. Let's break down the problem step by step.
To find out how many faces of the large cube are painted, we need to determine the total number of faces and then subtract the number of unpainted faces.
A cube has 6 faces in total. Each face of the cube represents one side. Therefore, to find the number of faces, we multiply the number of sides by the number of faces on each side.
Each face of the cube has the same dimensions, so they are identical. We can think of the cube as having 6 identical square faces.
Now, let's determine how many faces are painted and how many are unpainted based on the given information.
Given:
- Edge length of the cube: 12cm
Step 1: Determine the number of painted faces
To determine the number of faces that are painted, we need to consider how many sides of the cube are visible when it is painted. Typically, when an object is painted, only the outer surfaces are painted.
For a cube, the outer layer of the cube consists of all 6 faces. Therefore, all 6 faces would be painted.
So, the number of painted faces on the large cube is 6.
Step 2: Determine the number of unpainted faces
To determine the number of unpainted faces, we subtract the number of painted faces from the total number of faces (6).
Total number of faces - Number of painted faces = Number of unpainted faces
6 - 6 = 0
Therefore, the number of unpainted faces on the large cube is 0.
To summarize:
- Number of painted faces on the large cube: 6
- Number of unpainted faces on the large cube: 0
