perhatikan kerangka limas di samping.JIka tinggi limas 24 cm ,panjang kerangka limas tersebut.......cm

→ Diagonal Sisi Alas :
= √16² + 12²
= √256 + 144
= √400
= 20 cm
[ 1/2 Ds.Alas = 10cm ]

→ Sisi miring sisi tegak :
= √24² + 10²
= √576 + 100
= √676
= 26 cm

→ Panjang Kerangka Limas :
= 2 (p + l) + 4(sisi.tegak)
= 2 (16 + 12) + 4 (26)
= 2 (28) + 104cm
= 56 + 104cm
= 160 cm
