nomor 7 jawab ya pleas

V 1 = 6×6×6 = 216 cm3
V2 = 2×8×6 = 96 cm3
V3. = 6×6×6 = 216 cm3

Volume gabungan = 216+96+216= 528 cm3

volume Kubus I (kiri)
rusuk = 6 cm
volume kubus = r^3
volume =
6 x 6 x 6 = 216cm^3

volume Balok I (tengah)
panjang = 8 cm
lebar = 6 cm
tinggi = 2 cm
volume balok = p x l x t
volume =
8 x 6 x 2 = 96 cm^3

volume Kubus II (kanan)
volume =
6 x 6 x 6 = 216 cm^3

volume total = vol Kubus I + vol Balok I + vol Kubus II
= 216 + 96 + 216
= 528 cm^3
