Kak bantuin pls yg jago matematikaMenghitung volume limas segi empat pakai cara ya kak
Penyelesaian
1)
- Mencari tinggi limas
t² = 13² – (10 ÷ 2)²
t² = 169 – 5²
t = √(169 – 25)
t = √144
t = 12 cm
- Volume limas
V = 1/3 × La × t
V = 1/3 × s² × t
V = 1/3 × 10² × 12
V = 100 × 4
V = 400 cm³
2)
V = 1/3 × La × t
V = 1/3 × s² × t
V = 1/3 × 12 × 12 × 8
V = 4 × 12 × 8
V = 48 × 8
V = 384 cm³
