Penjelasan dengan langkah-langkah:
Misalkan :
A = Tinggi alas trapesium
t = tinggi prisma
A² = 20² - (28 - 16)²
A² = 20² - 12²
A² = 400 - 144
A² = 256
A = V256
A = 16
Luas alas trapesium = ½ x (16 + 28) x 16
Luas alas trapesium = ½ x 44 x 16
Luas alas trapesium = 352
Volume = Luas alas trapesium x t
Volume = 352 x 5
Volume = 1760 cm³
