Penjelasan dengan langkah-langkah:

dimensi tiga

AB = GH , BF = CG = 12 cm dan BC = FG = 9 cm

FH² = BH² - BF²

FH² = (15√2)² - 12²

FH² = 15² . 2 - 144

FH² = 225 . 2 - 144

FH² = 450 - 144

FH² = 306 ---> FH = √306

menentukan panjang GH = panjang balok

GH² = FH² - FG²

GH² = (√306)² - 9²

GH² = 306 - 81

GH² = 225 ---> GH² = 15² ---> GH = 15 cm

Volume balok:

V = AB x BC x CG = 15cm x 9cm x 12cm = 1620 cm³
