Jawaban:
1. 336cm²
2. 868cm²
Penjelasan dengan langkah-langkah:
1. Luas permukaan Limas
Luas permukaan = L. alas + (4×Luas segitiga)
= (s×s) + (4×1/2×a×t)
= (12×12) + (4×1/2×12×8)
= 144 + 192
= 336cm²
2. Luas permukaan Limas
= L.alas + (4×luas segitiga)
= (14×14) + (4×1/2×14×24)
= 196 + 672
= 868cm²
