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

### Instruction:
 John anajenga sanduku. Sanduku hilo lina urefu wa inchi 26, upana wa inchi 26, na kina cha inchi 14. Kuta zina unene wa inchi 1 kila upande. Ni kiasi gani cha ujazo wa ndani katika futi za ujazo?



### Response:
 Kuta zinapunguza inchi 2 kutoka kila upana. Hivyo upana mrefu ni inchi 26-2 = <<26-2=24>>24. Hiyo ni futi 24/12 = <<24/12=2>>2. Upana mdogo ni inchi 14-2 = <<14-2=12>>12. Hiyo ni futi 12/12 = <<12/12=1>>1. Hivyo ujazo wa ndani ni 2*2*1 = <<2*2*1=4>>4 futi za ujazo.
