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

### Instruction:
Gary is buying chlorine for his rectangular pool, which is 10 feet long, 8 feet wide, and 6 feet deep. Gary needs to buy one quart of chlorine for every 120 cubic feet of water in his pool. If chlorine costs $3 a quart, how much does Gary spend on chlorine?

### Response:
 Kwanza tafuta ujazo wa bwawa kwa kuzidisha urefu na upana na kina: 10 futi * 8 futi * 6 futi = <<10*8*6=480>>480 futi za ujazo
Kisha gawanya ujazo wa bwawa kwa idadi ya futi za ujazo ambazo robo lita moja ya klorini inaweza kusafisha: 480 futi za ujazo / 120 futi za ujazo/robo lita = <<480/120=4>>4 robo lita
Kisha zidisha idadi ya robo lita ambazo Gary anahitaji kununua na bei ya robo lita moja ili kujua kiasi cha pesa anachotumia: $3/robo lita * 4 robo lita = $<<3*4=12>>12
