✔ Mapel = Matematika✔ Bab = Bangun Ruang
✔ Materi = Limas
—————————————————
Penyelesaian :
a. Tinggi Limas
= √ (10² - (12/2)²)
= √ (100 - 36)
= √ 64
= 8 cm
Luas Alas
= s x s
= 12 cm x 12 cm
= 144 cm²
b. Luas Permukaan Limas
= Luas Alas + n(Luas Segitiga)
= 144 cm² + 4(1/2 x 12 cm x 10 cm)
= 144 cm² + 4(60 cm²)
= 144 cm² + 240 cm²
= 384 cm²
Semoga Membantu :)
