Based on the way these stations are connected, we can infer that there are <u>56 tubes. </u>
<h3>Number of tubes in Spaceland </h3>
Each pair of stations have 2 tubes. This means that every station is connected to each of the others.
We can therefore infer that each station has 7 tubes to the other stations.
The total number of tubes would therefore be:
= Number of stations x Number of tubes per station
= 8 x 7
= 56 tubes
In conclusion, there are 56 tubes.
