Below is an instruction that describes a task. Write a response that appropriately completes the request in Swahili. Please answer in Swahili.

### Instruction:
Vincent has 72 inches of rope that he wants to use for a project, but he needs to cut it into smaller pieces first. He cuts it into 12 equal length pieces, but then he realizes it's too short, so he ties three pieces together. The knots then make each piece 1 inch shorter. How long are his pieces of rope after all this?

### Response:
 Vincent anakata kamba ya inchi 72 katika vipande 12 sawa sawa, ambayo inamaanisha kila kipande ni urefu wa 72/12 = <<72/12=6>>6 inchi.
Vifungo katika vipande vilivyofungwa vinapunguza kila kipande inchi 1, kwa hivyo kila kipande ni 6 - 1 = <<6-1=5>>5 inchi.
Vipande vitatu vilivyofungwa pamoja sasa vina urefu wa 5 inchi x 3 = <<5*3=15>>15 inchi.
