Figure

Measuring and testing means

Folding rule, steel tape measure

Auxiliary accessories

Pocket calculator, paper, pencil

Required basic knowledge

Using length measuring instruments, mastering fundamental operations such as multiplying and dividing

Explanations to the working drawing

1 Mosaic parquetry-fillet
2 Parquetry-fillet
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 free-hand 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. Using a pocket calculator is recommended.
given: - dimensions of the room - dimensions of the surfaces of the parquetry-fillets
to be determined: - required number of mosaic parquetry-fillets - required number of parquetry-fillets
F₁ = a · b F₁ = 5030 mm · 5500 mm F1 =2 765 000 mm²	F₁ = surface without recess (total)
F₂ = a · b F₂ = 2100 mm ·2600 mm F₂ = 5 460 000 mm²	F₂ = surface of the recess
F_R = F₁ - F₂ F_R = 27 665 00 mm² - 5460 000 mm² F_R = 22 205 000 mm²	F_R = surface of the room (real)
4. Calculation of the surface of the given mosaic parquetry-fillet
F_MP = b · 1 F_MP = 20 mm · 120 mm F_MP = 2 400 mm²	F_MP = surface of the mosaic parquetry-fillet
5. Calculation of the surface of the given parquetry-fillet
F_SP = b · 1 F_SP = 60 mm · 400 mm F_SP = 24 000 mm²	F_SP = surface of the parquetry-fillet
6. Calculation of the required number of mosaic parquetry-fillets
MP = F_R : F_MP MP = (22 205 000 mm²)/( 2 400 mm²) MP = 9252.08	MP = mosaic parquetry-fillet
9300 mosaic parquetry-fillets are required.	Rounding the number up is necessary because waste material must be considered.
7. Calculation of the required number of parquetry-fillets
SP = F_R : F_SP SP = (22 205 000 mm²)/(24 000 mm²) SP 925.21	SP = parquetry-fillet
950 parquetry-fillets are required.
