Sisi miring segitiga = √12² + 5² = √144+25 = √169 = 13 cm
Luas Segitiga = 1/2 . a . t = 1/2 . 5 . 12 = 30 cm²
Keliling Segitiga = 12 + 5 + 13 = 30 cm

Luas Permukaan = 2 x Luas + Keliling x tinggi prisma
                            = 2 x 30 + 30 x 20
                            = 60 + 600
                            = 660 cm²

Volume = Luas alas x tinggi
             = 1/2 . a . t x tinggi
             = 1/2 . 24 . 7 . 15
             = 1.260 cm²
