### Instruction:
 Justin ana sanduku lenye urefu wa inchi 12. Urefu wa sanduku ni mara 3 ya urefu wake na mara 4 ya upana wake. Ni nini kiasi cha ujazo wa sanduku?


### Response:
 Urefu wa sanduku ni 3 x urefu wa inchi 12 = <<3*12=36>>36 inchi.
Upana wa sanduku ni 36 inchi / 4 = <<36/4=9>>9 inchi.
Urefu, urefu na upana wa sanduku ni inchi 12, inchi 36 na inchi 9, mtawalia.
Ujazo wa sanduku ni urefu x urefu x upana, au inchi 12 x inchi 36 x inchi 9 = <<12*36*9=3888>>3,888 inchi za ujazo.
