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 · bF1 = 5030 mm · 5500 mmF1 =2 765 000 mm2 F1 = surface without recess (total) F2 = a · bF2 = 2100 mm ·2600 mmF2 = 5 460 000 mm2 F2 = surface of the recess FR = F1 - F2FR = 27 665 00 mm2 - 5460 000 mm2FR = 22 205 000 mm2 FR = surface of the room (real) 4. Calculation of the surface of the given mosaic parquetry-fillet FMP = b · 1FMP = 20 mm · 120 mmFMP = 2 400 mm2 FMP = surface of the mosaic parquetry-fillet 5. Calculation of the surface of the given parquetry-fillet FSP = b · 1FSP = 60 mm · 400 mmFSP = 24 000 mm2 FSP = surface of the parquetry-fillet 6. Calculation of the required number of mosaic parquetry-fillets MP = FR : FMPMP = (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 = FR : FSPSP = (22 205 000 mm2)/(24 000 mm2)SP 925.21 SP = parquetry-fillet 950 parquetry-fillets are required.
