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

### Instruction:
 Tara ana sanduku la viatu lenye urefu wa inchi 4 na upana wa inchi 6. Anaingiza kibao cha mraba ndani ambacho kina upande wa inchi 4. Kiasi gani cha inchi mraba cha sanduku kimesalia bila kufunikwa?


### Response:
 Kibao cha mraba kinachukua inchi 4 x 4 = <<4*4=16>>16 za inchi mraba.
Sanduku lina inchi 4 x 6 = <<4*6=24>>24 za inchi mraba.
Hivyo, kibao kinaacha inchi 24 - 16 = <<24-16=8>>8 za inchi mraba bila kufunikwa.
