Asruul
Diketahui da = 24 cm tp = 40 cm Ka = 100 cm
pembahasan s = 100/4 = 25
db = 2√25-(½.24) db = 2√625-144 db = 2√481 db = √1924 db = 43,86 db ~ 44
V = La . tp V = ½ x 24 x 44 × 40 V = 21120 cm³
Lp = Kt + 2La LP = 100 x 40 + 2 x ½ x 24 x 44 Lp = 4000 + 1056 Lp = 5056 cm²
da = 24 cm
tp = 40 cm
Ka = 100 cm
