Step-by-step explanation:
⇒ Dimensions of a tin box =12cm×10.5cm×8cm
⇒ Here, l=12cm,b=10.5cm,h=8cm.
⇒ Total surface area of the sheet =2(lb+bh+lh)
⇒ Total surface area of the sheet =2(12×10.5+10.5×8+12×8)
⇒ Total surface area of the sheet =2(126+84+96)=2(306)=612cm

∴ Area of the sheet required to make 20 tins =20×612=12240cm
