Volume Balok:
V = Luas alas x tinggi balok
V = p x l x t
Volume Limas:
V = 1/3 x Luas alas x tinggi limas
Diketahui:
p balok = p limas = 16 cm
l balok = l limas = 16 cm
t balok = 5 cm
t limas = 6 cm
Ditanya: V
Jawab:
V = V balok + V limas
= (plt) + (1/3 x plt)
= (16 x 16 x 5) + (1/3 x 16 x 16 x 6)
= 1280 + (16 x 16 x 2)
= 1280 + 512
= 1792 cm³
Jadi, volume bangun tersebut adalah 1792 cm³.
Volume balok
V = p × l × t
V = 16 × 16 × 5
V = 256 × 5
V = 1.280 cm³
Volume Limas
V = ⅓ × Luas alas × tinggi Limas
V = ⅓ × (p × l) × 6
V = ⅓ × (16 × 16) × 6
V = ⅓ × 256 × 6
V = 256 × 2
V = 512 cm³
Volume gabungan
1.280 + 512
= 1.792 cm³
