Jawab:
a. 216 cm²
b. 192 cm²
Penjelasan dengan langkah-langkah:
Luas alas = 1/2 x a x t
Luas alas = 1/2 x 8 x 6
Luas alas = 4 x 6
Luas alas = 24 cm²
keliling alas = s1 + s2 + s3
keliling alas = 8 + 6 + 10 = 24 cm
a . Lp = (2 x La) + (Ka x t)
Lp = (2 x 24) + (24 x 7)
Lp = 48 + 168 = 216 cm²
b . La tanpa tutup = La + (Ka x t)
La tanpa tutup = 24 + 168 = 192 cm²
semoga membantu^^
