2 dm kubik + 800 cm kubik - 0,05 liter =....milliliter

2dm kubik = 2000 ml
800 cm kubik = 80ml
0.05liter = 50 ml

2000 + 80 - 50
=2030

jadi hasil nya adalah 2030 ml

2 dm² + 800 cm³ - 0,05 l = (2 x 1000) + (800 x 1) - (0,05 x 1000)
                                       = 2000 + 800 - 50
                                       = 2800 - 50
                                       = 2750 ml

Semoga Membantu :)
