826 ha=826 hm²=82600dam²=8260000m²
225000000m³=225000000000 dm³=225.10^9 dm³=225.10^9l
225000000m³=225000000000 dm³=225.10^9 dm³=225.10^9l
a) 826 ha=826hm²=8260000m²
b)225 * 1000000m³ = 225000000m³=225000000000dm³=225000000000 litri .
b)225 * 1000000m³ = 225000000m³=225000000000dm³=225000000000 litri .
