Question

1. bak mandi berbentuk balok dng daya tampung 288 liter air. jika perbandingan p:l:t =6:3:@ maka lebar bak mandi adalah ...

Answer 1

V=P*l*T
288=6*3*@
288=18*@
@=288/18
   =16

Answer 2

V= 288L = 288dm³
P:L:t = 6a : 3a : 2a

PxLx T = 288
6a x 3a x 2a = 288
36a³ = 288
a³ =288/36 =8
a =∛8 = 2

P= 6a =6(2) = 12dm
L = 3a = 3(2) =6 dm = 60cm
t= 2a = 2(2) = 4dm
