John builds a box.  The box is 26 inches by 26 inches by 14 inches.  The walls are 1 inch thick on each side.  How much is the internal volume in cubic feet?
How many inches are the walls? ** The walls take away 2*1=<<2*1=2>>2 inches from each dimension
How long are the longer sides? ** So the longer sides are 26-2=<<26-2=24>>24 inches
How long are the longer sides? ** That is 24/12=<<24/12=2>>2 feet
How small is the smaller dimension? ** The smaller dimension is 14-2=<<14-2=12>>12 inches
How small is the smaller dimension? ** That is 12/12=<<12/12=1>>1 foot
How much is the internal volume in cubic feet? ** So the internal volume is 2*2*1=<<2*2*1=4>>4 cubic feet
