Tolong kak plis nanti aku kasih poin
luas alas limas persegi panjang = panjang × lebar
a = 12cm × 6cm
a = 72cm²
volume = 1/3 × luas alas × tinggi limas
volume = 1/3 × 72cm × 8cm
volume = 1/1 × 24cm × 8cm
volume = 24cm × 8cm
volume = 192cm³
luas alas = panjang × lebar
a = √a² + b² = c²
a = √12² + 6² = c²
a = √(12 × 12) + (6 × 6) = c²
a = √144 + 36 = 180²
a = √180² = √180 × 180
a = √32.400
a = 180cm²
luas permukaan limas persegi panjang = luas alas + (4 × luas segitiga)
lp = 180 + (4 × 1/2 × ts)
lp = 180 + (4 × 1/2 × 8)
lp = 180 + (4 × 4)
lp = 180 + 16
lp = 196cm²
