kakak..soal nmr 1 ama 2 tlg dgn caranya please kakak...

1. 180cm³
    Panjang   = 4xlebar        = 4     x 3cm  =12cm
    Tinggi      = 2cm+lebar   = 2cm + 3cm = 5cm
    Lebar       = 3cm
    Volume    = p x l x t = 12cm x 3cm x 5cm = 180cm³

2. 1.100cm³
    Volume I  = p x l x t = 14cm x 10cm x 5m = 700cm³ (Balok bawah)
    Volume II = p x l x t = 10cm x (14cm-6cm) x (10cm-5cm)
                                   = 10cm x 8cm x 5cm = 400cm³
    Volume keseluruhan = 700cm³ + 400cm³ = 1.100cm³
