IVh. Project Keys

[Paint] - Computes volume of paint ( in gallons /

quarts / pints ) basing on the
entered area and a stored value of
Paint Coverage per Gallon.

- Computes the area covered by the
defined Paint Coverage per Gallon.

[Wallpaper] - Computes number of rolls of wallpaper

basing on an entered area and a
stored value of “Wallpaper Roll
Coverage Area”.

- Calculate the wall area to be covered
by the entered number of rolls of
wallpaper.

[Tile] - Find the number of tiles, based on an

entered area and a user-stored Grout
Width. Repeated presses will scroll
between numbers of tiles for various
standard tile sizes (12” / 13” / 16” / 18”
/ 24” / 1” / 2“ / 4” / 6” / 8” / 10”).
