एक समान शिरोबिंदू सामायिक करणाऱ्या घनाच्या तीन मुखांचे पृष्ठभाग क्षेत्र 25 m², 32 m² आणि 32 m² आहेत. घनदाटाची मात्रा किती आहे?
A160 m³
B92 m³
C184 m³
D128 m³
Answer & Solution
Correct answer: A. 160 m³
1.
चेहरे ab = 25, bc = 32, ca = 32 असू द्या.
2.
गुणाकार: (abc)² = 25 × 32 × 32 = 25600.
3.
तर abc = √25600 = 160.
4.
घनदाट = abc = 160 m³.
