Answer:
Explanation:
The original dimensions of the cuboid are 6cm, 9cm, and 12cm. To find the new dimensions after reducing the cuboid by a scale factor of 3, we need to divide each dimension by the scale factor.
So, the new length of the cuboid would be 6cm divided by 3, which equals 2cm.
The new width would be 9cm divided by 3, which equals 3cm.
And the new height would be 12cm divided by 3, which equals 4cm.
Therefore, the new dimensions of the cuboid after reducing it by a scale factor of 3 would be 2cm, 3cm, and 4cm.
