anonymous · Answer

4 x (small band size finished length + 3/4 in) + 5 x (medium band size finished length + 3/4 inch) + 3 x (large band size finished length + 3/4 inch) = total strip length Estimate by rounding. 21 3/8 + 3/4 can be estimated to be around 22 inches 23 1/8 + 3/4 approximately equal to 24, and 24 1/4 + 3/4 = 25 so estimate 4 (22) + 5 (24) + 3 (25) = 283
