$\huge\bold\red{Answer}$

Formula,

• Total Surface Area of cuboid = 2( lb + bh + hl ).

Given,

• Length = 40cm
• Breadth = 30cm
• Height = 25cm

=> Solution:

Surface Area = 2 (40×30 + 30×25 + 25×40 )

= 2 (1200 + 750 + 1000 )

= 2( 2950 )

= 5900 cm^2.

= 2[1200 + 750 + 1000]

= 2 × 2950

= 5900 cm^2
