Tolong ya jawab soal yg di atas cuma 2
24. Balok dg p = 12cm, l = 10cm, t = 7cm
Volume?
Vbalok = p × l × t = 12 × 10 × 7 = 840cm^2
26. Gambar terlampir
• Dua segitiga (alas dan atap)
L2segitiga = 6 × 8= 48cm^2
• Sisi tegak 1
Ls1 = 8 × 19 = 152cm^2
• Sisi tegak 2
Ls2 = 6 × 19 = 114cm^2
• Sisi tegak 3
Ls3 = 10 × 19 = 190cm^2
Total LP = 48 + 152 + 114 + 130 = 504cm^2
Semoga membantuu:)
