Detailed Solution

माना लंबाई, चौड़ाई और ऊँचाई के प्रारंभिक मान है
100, 100 और 100
परिवर्तन के बाद,
लंबाई = 120
चौड़ाई = 125
और ऊँचाई = 70
अब, प्रारंभिक आयतन = 1000000
और अंतिम आयतन
= 120 × 125 × 70
= 1050000
अब, प्रतिशत परिवर्तन
= (1050000 - 1000000) × 100/1000000
= 50000 × 100/1000000
= 5%
इसलिए, अभीष्ट मान 5% है।
