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

Convert m to cm:
0.5 m = 0.5 x 100 = 50 cm
.
Find Surface Area:
Surface area = 2( 50 x 25 ) + 2 (25 x 15 ) + 2 (15 x 50 )
Surface area = 2500 + 450 + 1500
Surface area = 4450 cm²
.
Answer: Total surface area = 4450 cm²
