Mario broke a pane of glass in a window.The opening measured 7 and 1/4 inches by 9 and 1/2 in.At the hardware store,they sold him a pane of glass that was 7 and 1/4 inches by 9 and 1/2 inches to the nearest 1/4 inches.Can Mario be sure the glass will fit the window?And why
No. The glass measures to the nearest quarter of an inch, which means the measurements could be as much as 1/8 inch too big or two small in each directions.
No. Without a zero tolerance for larger dimensions, it could be larger than the opening. A clearance (smaller size) with a zero tolerance above 7 1/8 by 9 3/8 should have been specified.
Hardware stores should be able to provide +/- 1/8" tolerance (maximum error) on cut glass.
