John o na le mabokoso a le 3. Lebokoso le leng le le leng le bogolo jwa di-inches di le 5 ka bophara, di le 6 ka bolelele le di le 4 ka bogolo. Mabota a mabokoso a bogolo jwa inchi e le 1.  Bogolo jo bo ka fa gare ga mabokoso otlhe a le 3 ke bo kae?

John has 3 boxes.  Each box is 5 inches by 6 inches by 4 inches.  The walls are 1 inch thick.  What is the total inner volume of all 3 boxes?
Mabota a fokotsa bogolo jwa di-inches di le 2*1=<<2*1=2>>2 mo go lengwe le lengwe la mabokoso
Ka jalo lebokoso le leng le le leng le nna le bophara jwa di-inches di le 5-2=<<5-2=3>>3
Le bolelele jwa di-inches di le 6-2=<<6-2=4>>4
Mme bogolo jwa lona e nne di-inches di le 4-2=<<4-2=2>>2
Ka jalo bogolo jwa lebokoso le le lengwe ke 4*3*2=<<4*3*2=24>> di-cubic inches di le 24
Jalo bogolo jotlhe jwa mabokoso a le 3 ke 3*24=<<3*24=72>> di-cubic inches di le 72

The walls subtract 2*1=<<2*1=2>>2 inches from each dimension
So each box has 5-2=<<5-2=3>>3 inch width
It also has a 6-2=<<6-2=4>>4 inch height
Finally, it has a 4-2=<<4-2=2>>2 inch depth
So the inner volume of one box is 4*3*2=<<4*3*2=24>>24 cubic inches
So in total the inner volume of the 3 boxes is 3*24=<<3*24=72>>72 cubic inches
