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

### Instruction:
Lorenzo put three full cans of thumbtacks into his pocket and went off to work at the corkboard factory. It was Lorenzo's job, as head of quality control, to test every cork board for its ability to hold thumbtacks.  He placed one thumbtack from each of the three cans of thumbtacks into every board tested.  At the end of the day, he had tested 120 boards and had 30 tacks remaining in each of the three cans.  What was the total combined number of thumbtacks from the three full cans?

### Response:
 Mwishoni mwa siku, alikuwa amefanya majaribio ya ubao 120, kila mmoja na pini tatu, kwa jumla ya pini 120*3=<<120*3=360>>360.
Ikiwa alikuwa na pini 30 zilizobaki katika kila moja ya makopo matatu ya pini, alikuwa na jumla ya pini 3*30=<<30*3=90>>90 zilizobaki.
Hivyo, jumla ya awali ya pini kutoka kwenye makopo matatu kamili ya pini ilikuwa 360+90=<<360+90=450>>450 pini.
