Tentukan volume bangun diatas ini no. 1dan 2

1. jawab :

V1 = r × r × r = 4 × 4 × 4 = 64 cm 

V2 = p × l × t = 12 × 4 × 4 = 192 cm

V = V1 + V2 = 64 + 192 = 256 cm

2. Jawab :

V1 = p × l × t = 10 × 5 × 5 = 250 cm

V2 = p × l × t = 15 × 5 × 5 = 375 cm

V = V1 + V2 = 250 + 375 = 625 cm

- maaf kalau ada yang salah :)

1)
Volume kubus
s = 4 cm

V = s³
V = (4 cm)³
V = 64 cm³

Volume balok
p = 12 cm
l = 4 cm
t = 4 cm

V = p x l x t
V = 12 cm x 4 cm x 4 cm
V = 192 cm³

Volume keseluruhan
V = 64 cm³ + 192 cm³
V = 256 cm³

2)
Volume = V.balok1 + V.balok2
V = (p1 x l1 x t1) + (p2 x l2 x t2)
V = (10 cm x 5 cm x 5 cm) + (15 cm x 5 cm x 5 cm)
V = 250 cm³ + 375 cm³
V = 625 cm³
