Explanations to the working drawing
1 Mosaic parquetryfillet
2 Parquetryfillet
3 Surface of
the room to be calculated
Sequence of operations 
Comments 
1. Preparing writing paper, pencil and measuring equipment. 
Taking this equipment to the room that shall be measured. 
2. Measuring the dimensions of the room and writing them down on a hand drawing. 
Making the freehand sketch in the room itself (“on the spot”). 
3. Calculating the surface of the room 
The calculations should be made at a working table with
seats. 
given: 

to be determined:  
F_{1} = a ·
b 
F_{1} = surface without recess (total) 
F_{2} = a ·
b 
F_{2} = surface of the recess 
F_{R} = F_{1}  F_{2} 
F_{R} = surface of the room (real) 
4. Calculation of the surface of the given mosaic parquetryfillet  
F_{MP} = b ·
1 
F_{MP} = surface of the mosaic parquetryfillet 
5. Calculation of the surface of the given parquetryfillet  
F_{SP} = b ·
1 
F_{SP} = surface of the parquetryfillet 
6. Calculation of the required number of mosaic parquetryfillets  
MP = F_{R} : F_{MP} 
MP = mosaic parquetryfillet 
9300 mosaic parquetryfillets are required. 
Rounding the number up is necessary because waste material must be considered. 
7. Calculation of the required number of parquetryfillets 

SP = F_{R} : F_{SP} 
SP = parquetryfillet 
950 parquetryfillets are required.
