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

### Instruction:
Tom was putting hardwood flooring into his living room that measured 16' long and 20' wide.  The flooring comes 10 sq ft per box and he has already put down 250 sq ft of flooring.  How many more boxes does Tom need to complete the job?

### Response:
 16x20 = <<16*20=320>>320 futi za mraba
Futi za mraba 250 zimekwisha, futi za mraba 320 zinahitajika = 320-250 = <<320-250=70>>70 futi za mraba
70 futi za mraba / 10 futi za mraba kwa kisanduku = <<70/10=7>>7 kisanduku zaidi
