Hola friends!!
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..
