Hey friend!!
Here's ur answer...
____________________
Length = 80 cm.
Breadth = 30 cm.
Height = 40 cm.
Required area = area of side faces + area of base + area of blackface
= 2 ( 40 × 30) + (80 × 30) + ( 80 × 40)
= 2 ( 1200) + 2400 + 3200
= 2400 + 2400 + 3200
= 8000 cm ².
So, option (2) is correct.
