Answer 1

Answer:

ANSWER

Given, Length of the cuboid (l)=15cm

Breadth of the cuboid (b)=12cm

Height of the cuboid (h)=10cm

Surface area of a cuboid =2(lb+bh+hl)

=2(15×12+12×10+10×15)cm²

=2(180+120+150)cm²

=2(450)cm²

=900cm²

Answer 2

Answer:

Surface area of Cuboid = 2(lb + bh + hl)

= 2{(15 × 12) + (12 × 5) + (5 × 15)}

= 2(180 + 60 + 75)

= 2 × 315

= 630 cm²
