Комната имеет размеры 4,2 м на 3,6м какое количество пачек ламината нужно купить, если в одной пачке 1,7кв. м. ламината ​

1 см³ - 100 мм³ = 1.000 мм³ - 100 мм³ = 900 мм³ = 0,9 см³

1 дм³ - 200 см³ = 1 дм³ - 0,2 дм³ = 0,8 дм³

100 м² + 2 га = 100 м² + 20.000 м² = 20.100 м²

800 а : 2 = 400 а

1 000 см³ - 1 дм³ = 1.000 см³ - 1.000 см³ = 0 см³

400 м² : 4 = 100 м²

200 дм³ + 100 м³ = 200 дм³ + 100.000 дм³ = 100.200 дм³

10 см³ + 1.000 см³ = 1.010 см³

5 м³ : 100 дм³ = 5.000 дм³ : 100 дм³ = 50 дм³ = 0,05 м³

500 м³ + 100 дм³ = 500.000 дм³ + 100 дм³ = 500.100 дм³ = 500,1 м³

5 м³ + 100 дм³ = 5.000 дм³ + 100 дм³ = 5.100 дм³ = 5,1 м³

50 м² + 100 дм² = 5.000 дм² + 100 дм² = 5.100 дм² = 50,1 м²
