HP 11C: Construction: Calculating the Number of Tiles
Introduction
The 11C program presented will calculate the number of tiles needed for a rectangular room given:
* room length and width, in feet
* tile length and width, in feet
* grout applied, if any, in inches
* waste allowance %
For example, for a room of dimensions 12 feet 6 inches by 16 feet 8 inches, enter the room dimensions as 12.5 (12 + 6/12) and 16.66666667 (16 + 8/12), respectively.
Instructions:
Outside of User Mode:
Enter room length [ENTER] room width [ f ] [ A ]
Enter tile length [ENTER] tile width [ f ] [ B ]
Enter grout width [ f ] [ C ]
Enter waste allowance [ f ] [ D ]
Calculate the number of tiles, [ f ] [ E ]
In User Mode:
Enter room length [ENTER] room width [ √ ] (A)
Enter tile length [ENTER] tile width [ e^x ] (B)
Enter grout width [ 10^x ] (C)
Enter waste allowance [ y^x ] (D)
Calculate the number of tiles, [ 1/x ] (E)
Variables:
R1 = tile length (ft)
R2 = tile width (ft)
R3 = grout (in)
R4 = room length (ft)
R5 = room width (ft)
R6 = waste %
Number of tiles =
ceiling( (room length * room width) / ((tile length + grout) * (tile width + grout)) * (1 + waste%)
ceiling: next highest integer
