Question

length= 30cm, breadth=15cm and height=15cm.find the surface area of the cuboid

Answer 1

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 ) ;
