Penjelasan dengan langkah-langkah:

1.

a. 7, 8, 9, 10

b. 12, 14, 16, 18

c. 7, 8, 9, 10

d. 9, 14, 20, 27

e. 0, 0, 0, 0

f. 9, 14, 20, 27

2. sisi alas = 192/4 = 48 cm

rusuk tegak = √10²+(½.48)² = √100+576 =√676 = 26 cm

panjang kerangka = 192 + 4.26 = 192 + 104 = 296 cm

3. panjang kerangka = 4.20+4.24 = 80+96 = 176 cm

4. tinggi ∆ = √8²+(½.24)² = √64+144 = √208. cm

rusuk tegak = √(½.18)²+208 = √81+208 = 17 cm

panjang kerangka = 24+18+24+18+4.17 = 152 cm
