Matematika ¤ Bab = Bangun Ruang ¤ Materi = Volume ---------------------------------------------- ✌ Diket : Panjang = 12 cm Lebar = 9 cm Volume = 864 cm³
Penyelesaian :
Volume = p x l x t 864 cm³ = 12 cm x 9 cm x t 864 cm³ = 108 cm² x t t = 864 cm³ / 108 cm² t = 8 cm
Semoga Membantu :)

A. Tinggi balok = 864 cm ÷ 12 cm ÷ 9 cm = 8 cm
B. luas permukaan balok = (2×p×l)+(2×p×t)+(2×l×t) = (2×12×9)+(2×12×8)+(2×9×8) = 216 + 192 + 144 = 552 cm2

Diket :
Panjang = 12 cm
Lebar = 9 cm
Volume = 864 cm³
Penyelesaian :
Volume = p x l x t
864 cm³ = 12 cm x 9 cm x t
864 cm³ = 108 cm² x t
t = 864 cm³ / 108 cm²
t = 8 cm
