Question

(tolong bantuannya) butuh banget

Answer 1

Wlampu = 10 x4 x10 = 400
WTv = 100 x 1 x 10 = 1000
Wseterika = 300 x 1 x 2 = 600
400 + 1000+ 600 = 2000
2000 x 30 hari = 60.000 W = 60 Kwh

Answer 2

10 x 4 x10 = 400
100 x1 x10 =1000
300 x1 x 2 = 600
= 2000 x 30( dari satu bulan 30 hari )
= 60000/1000 =60 KWH
