Here is your answer :

Length l of cardboard box = 0.5 m = 50 cm

Breadth b of cardboard box = 25 cm

Height h of cardboard box= 15 cm

Total surface area of cardboard box

=> 2 ( lb + bh + hl)

=> 2 ( 50 × 25 + 25 × 15 + 15 × 50 )

=> 2 ( 1250 + 375 + 750 )

=> 2 ( 2375 )

=> 4750 cm²

HOPE IT HELPS YOU..

Answer 2

TSA OF THE CARDBOARD BIX = 2(lb+bh+hl)

= 2(4 X75 + 75 X 50 + 4 X 50)

= 2(300+3750+200)

= 8500cm²
