Solution

To solve this problem, we first need to find the weight of the pipe per meter.

Step 1: Divide the weight of the 3-meter pipe by its length to find the weight per meter. 7.6 kg / 3 m = 2.533 kg/m

Step 2: Multiply the weight per meter by the length of the 7.8-meter pipe to find its weight. 2.533 kg/m * 7.8 m = 19.7574 kg

So, a 7.8-meter pipe of the same kind would weigh approximately 19.76 kg.
