41.200 m²= 412 are
300 dam²= 300 are
3 hektare= 300 are

41.200 m² + 300 dam² + 3 hektare=
412 + 300 + 300=
1.012 are

2,7 liter= 2.700 cm³
4 dm³= 4.000 cm³

2,7 liter + 4 dm³=
2.700 + 4.000=
6.700 cm³

Soal pertama
- Volume kubus1 dan kubus2 = 512cm³
V = s³
512 = s³
s = ∛512
s = 8cm
- Volume kubus3 = 125cm³
V = s³
125 = s³
s = ∛125
s = 5cm

Tinggi tumpukan kubus = 8 + 8 + 5 = 21cm

Soal kedua
41.200 m² + 300 dam² + 3 hektare/ha = ... are
412 are + 300 are + 300 are = 1.012 are

Soal ketiga
2,7 liter + 4 dm³ = ... cm³
2.700 cm³ + 4.000 cm³ = 6.700 cm³

Soal keempat
72 km/jam = ... m/detik
72 x 1.000/3.600 = 72.000/3.600 = 20 m/detik

Semoga membantu.
