Presentation Transcript

  1. Sala 127 Gabriela Jaworska Olga Jakubiak Katarzyna Floriańczyk Sylwia Gąsławska Anna Zawada Magdalena Całka Natalia Bajorek kl. 2d1

  2. SUFIT P = 3,75 * 5,78= = 21,675 m2

  3. OKNO P = 1,7 * 2,24 = 3,808m2 Pwnęki = 0,38 * 1,7 + + 2 * 0,38 * 2,24 = 0,646 + + 1,7024 = 2,3484 m2

  4. DRZWI P = 2,06 * 1,07 = 2,2042m2 Pwnęki = 1,07 * 0,5 + 2 * * 2,06 * 0,5 = 0,535 + 2,06= = 2,595 m2

  5. ŚCIANY P1 = 3,5 * 5,78 = 20,23 m2 P2 = 3,75 * 3,5 = 13,125 m2

  6. PODSUMOWANIE P do odliczenia = 2,2042 + 3,808 = 6,0122 m2 P całkowite = 21,675 + 2 * 20,23 + 2 * 13,125 + 2,3484 + 2,595 = 21,675 + 40,46 + 26,25 + 2,3484 + 2,595 = 93,3284 m2 P do pomalowania = 93,3284 – 6,0122 = 87,3162 m2 malujemy dwa razy 87,3162 m2 * 2 = 174,6324 m2 do pomalowania

  7. 1 litr farby starcza na 10m2 Skoro do pomalowania mamy 174,6324 m2 to musimy zakupić 17,5 l farby. Przyjmując, że: • 5 l farby Dulux „Barwy natury” kosztuje 69,90 zł • 2,5 l farby Dulux „Barwy natury” kosztuje 39,50 zł to całkowity koszt pomalowania sali wyniesie 69,90 zł * 3 + 39,50 zł = 249,20 zł

  8. Sala 127 będzie pomalowana na taki kolor: „las równikowy”
