हें . एक समान शिखर वांटून घेवपी घनरूपाच्या तीन तोंडांचे पृश्ठभाग 25 m², 32 m² आनी 32 m² अशे आसात. घनद्रव्याचें आयतन कितलें आसता?
A160 m³
B92 m³
C184 m³
D128 m³
Answer & Solution
Correct answer: A. 160 m³
हें .
1 हें नांव.
मुखामळां ab = 25, bc = 32, ca = 32 आसूं.
2 हें नांव.
गुणाकार करात: (abc)² = 25 × 32 × 32 = 25600.
3 हें नांव.
म्हणजे abc = √25600 = 160.
4 हें नांव.
घनरूपाचें आयतन = abc = 160 m³.
