Bhai, agar tera kitchen scale bhi thoda gol-gol bata raha hai aur measuring jug mein aankh se andaza lagana pad raha hai, toh density ka error dono errors ko jod de. Maan lo, jaise mere purane machine ka vibration stitching mein fark la deta hai, waise hi mass aur volume ke chhote errors milkar density mein bada hisaab bigaad dete hain. Main to ek kapde ki strip kaat ke uska weight aur size leke dekh leta hoon, taaki pata chal jaaye kitna farak pad raha hai asli cheez se.
