Hlo friend.. Cutiepie Here.. L
Here is ur answer :
Length l of cuboid = 30 cm
Breadth b of cuboid = 15 cm
Height h of cuboid = 15 cm
_________________________________
Lateral surface area of cuboid = 2h ( l + b)
= 2 × 15 ( 30 + 15 )
= 30 ( 35 )
= 1050 cm²
_________________________________
Total surface area of cuboid = 2 ( lb + bh + hl )
= 2 ( 30 × 15 + 15 × 15 + 30 × 15 )
= 2 ( 450 + 225 + 450)
= 2 ( 1120 )
= 2240 cm²

Hello,
se calculate the surface area of the cuboi with che formul:
As = 2×( lb + bh + hl );
= 2 ( 30 × 15 + 15 × 15 + 30 × 15 ) ;
= 2 ( 450 + 225 + 450) ;
= 2 ( 1120 ) ;
= 2240 cm²
The surface of the cuboid is 2240 cm²
bye :-)
