tolong dijawab kak.....pake caranya nomor 7&8

7. volume balok = p x l x t
V = 6 x 5 x 4
V = 120 cm³
volume prisma segitiga = ½ x a x t x T
V = ½ x 5 x 3 x 6
V = 45 cm³
Volume total = volume balok + volume prisma segitiga
Vt = 120 + 45
Vt = 165 cm³

8. volume prisma segitiga 1 = ½ x a x t x T
V1 = ½ x 4 x 3 x 10
V1 = 60 cm³
volume prisma segitiga 2 = ½ x a x t x T
V2 = ½ x 5 x 5 x 3
V2 = 37,5 cm³
Volume total = V1 + V2
Vt = 60 + 37,5
Vt = 97,5 cm³
