First what you will want to do is convert all the widths to inches so that it’s easier to work with (i’ll let you convert them yourself). then after you have converted all of them, add all the widths up. (8 1/4 inches + 1 1/2 feet + 1 foot 3 5/6 inches). Once you do that, you know that there will be 2 inches between each frame, which would allow for 4 inches of extra width to be added to the total of the frame widths that u calculated before. after you add 4 inches to the previous total you calculated, that’s uour answer!
