ಘನದ ಅಂಚನ್ನು ಅರ್ಧಮಟ್ಟಕ್ಕಿಳಿಸಿದರೆ, ಅದರ ಪರಿಮಾಣವು ಮೂಲ ಪರಿಮಾಣಕ್ಕಿಂತ ಎಷ್ಟು ಪಟ್ಟು ಕಡಿಮೆಯಾಗುತ್ತದೆ?

A1/3
B1/4
C1/8
D1/2
Answer & Solution
Correct answer: C. 1/8
1. ಘನದ ಪರಿಮಾಣ = (ಅಂಚು)^3. 2. ಅಂಚನ್ನು ಅರ್ಧದಷ್ಟು ಮಾಡುವುದರಿಂದ ಪರಿಮಾಣ = (ಅಂಚು/2)^3 = (ಅಂಚು)^3 / 8. 3. ಆದ್ದರಿಂದ ಹೊಸ ಸಂಪುಟವು ಮೂಲದ 1/8 ಆಗಿದೆ. _ಮೂಲ: RRB ಗುಂಪು D CEN-02/2018 PYQ, Q.12._
