6 km² = 6 (1000m)² = 6 000 000 m
300 cm² = 300 (1/100)²= 300 (1/10000) =0,03 m²
30 dm² = 30(1/10)² =30(1/100) = 0.3 m²
163 cm² = 163 *10² =16300 mm²
0,25m² = 0,25* (10 000)² = 25 000 000 mm²
80cm² = 80 *10² = 8000 mm²
300 cm² = 300 (1/100)²= 300 (1/10000) =0,03 m²
30 dm² = 30(1/10)² =30(1/100) = 0.3 m²
163 cm² = 163 *10² =16300 mm²
0,25m² = 0,25* (10 000)² = 25 000 000 mm²
80cm² = 80 *10² = 8000 mm²
