ಸಾಮಾನ್ಯ ಶೃಂಗವನ್ನು ಹಂಚಿಕೊಳ್ಳುವ ಘನಾಕೃತಿಯ ಮೂರು ಮುಖಗಳ ಮೇಲ್ಮೈ ಪ್ರದೇಶಗಳು 25 m², 32 m² ಮತ್ತು 32 m². ಘನಾಕೃತಿಯ ಪರಿಮಾಣ ಎಷ್ಟು?
A160 m³
B92 m³
C184 m³
D128 m³
Answer & Solution
Correct answer: A. 160 m³
1.
ಮುಖಗಳು ab = 25, bc = 32, ca = 32 ಆಗಿರಲಿ.
2.
ಗುಣಿಸಿ: (abc)² = 25 × 32 × 32 = 25600.
3.
ಆದ್ದರಿಂದ abc = √25600 = 160.
4.
ಘನಾಕೃತಿಯ ಪರಿಮಾಣ = abc = 160 m³.
