Mencari sisi miring segitiga.
x^2=8^2+15^2 \\ x^2=64+225=289 \\  x= \sqrt{289} =17 cm

luas permukaan = 2 x luas alas + keliling alas x tinggi prisma
520 = 2 (1/2 x 8 x 15) + (8+15+17) x tp
520 = 120 + 40.tp
520-120=40tp
400=40tp
tp=400/40 = 10 cm

volume= luas alas x tinggi
V=\frac{1}{2} . 8 . 15.10 = 600 cm^3
