Jawaban:
Lp balok = 2 × ( pl + pt + lt)
= 2 × [ ( 24 × 10 ) + ( 24 × 12 ) + ( 10 × 12) ]
= 2 × ( 240 + 288 + 120)
= 2 × 648
= 1.296 cm³
Lp limas = L alas + L smua sisi
= ( s × s) + ( 4 × ( a × t / 2)
= ( 10 × 10) + ( 4 × ( 10 × 15 / 2)
= 100 + ( 4 × 75)
= 100 + 300
= 400 cm³
Lp gabungan = 1.296 + 400 = 1.696 cm³
