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

### Instruction:
Kevin's fish tank was leaking slowly at a rate of 1.5 ounces per hour.  He planned to go to the fish tank store later that day to get a new tank, but it may be as long as 12 hours before he can return home with the new tank.  Therefore, to collect the leaking fluid over that time, he placed a bucket underneath the tank that could hold twice the amount of fluid that would leak over 12 hours.  What size bucket, in ounces, did he use?

### Response:
 Ikiwa unsi 1.5 unavuja kwa saa na itachukua masaa 12 kabla hajarejea, basi unsi 1.5/saa * masaa 12 = <<1.5*12=18>>18 unsi zitavuja.
Ikiwa ndoo inaweza kuhifadhi mara mbili ya kiasi hicho, basi ndoo lazima iweze kuhifadhi 2 * 18 unsi = <<2*18=36>>36 unsi.
