A Classroom bulletin board is 7 feet by 4 feet. If there is a picture of a student every 6 inches along the edge, including one in each corner, how many pictures are on the bulletin board? The teacher gave me the answer 40 but I don't know how.... Can you help me, please

Looks wrong to me.
2 pictures per foot, so that's 14 pics along the top and bottom (counting the corners), and
6 pictures along each side (not counting the corners)
14+14+6+6 = 40
