Penjelasan dengan langkah-langkah:
luas permukaan prisma = 2 x luas alas + keliling las x tinggi
= 2 x (16 x 20/2) + (12 + 16 + 20 ) x 18
= 16 x 20 + 48 x 18
= 320 + 864
= 1.184 cm²
V = 1/2 × a × t × tp
V = 1/2 × 12 × 16 × 18
V = 12 × 16 × 9
V = 1. 728 cm³
L = (2 × luas alas) + (k. alas × t. prisma)
L = (2 × 1/2 × 12 × 16) + (16+12+20) × 18)
L = 192 + (864)
L = 1.056 cm²
