समजा लांबी, रुंदी आणि उंचीची प्रारंभिक मूल्ये 100, 100 आणि 100 ही आहेत
नंतर बदल केल्यानंतर,
लांबी = 120
रुंदी = 125
आणि उंची = 70
आता, प्रारंभिक घनफळ = 1000000
आणि अंतिम घनफळ
= 120 × 125 × 70
= 1050000
आता, टक्केवारी बदला
= (1050000 - 1000000) × 100/1000000
= 50000 × 100/1000000
= 5%
म्हणून, आवश्यक मूल्य 5% आहे.
Shortcut Trick
वाढलेले घनफळ% = 10/200 × 100 = 5%
