In total there are 120 dots on the edges of a cube.
Given that, a cube has an edge length of 10 cm. Starting at the vertices dots are placed along every edge at 1 cm intervals.
We need to find how many dots will there be in total once the pattern has been completed.
How many edges are there in the cube?
The number of edges in the cube is 12.
Now, the number of dots on an edge of 10 cm has 10 dots.
The total number of dots = Number of dots on an edge × Number of edges in a cube.
=10×12=120.
Therefore, in total there are 120 dots on the edges of a cube.
