Question

The inside of an open metal box of
internal dimensions 25 cm x 18 cm x
15 cm is lined with paper. Find the area of
the paper required ​

Answer 1

answer:2190cm2

explaination:

length=25cm

breadth=18cm

height=15cm

then,the area of paper required=area of cuboid

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

=2(25×18+18×15+15×25)

=2(450+270+375)

=2(1095)

=2190cm2

therefore,the area of paper required is 2190cm2

Answer 2

Answer:

2190cm^2

Step-by-step explanation:

in cuboidal box

length=25cm

breadth=18cm

height=15cm

area of sheet required=TSA of cuboid

=2(lb+bh+hl)

=2(25×18+18×15+15×25)

=2(450+270+375)

=2(1095)

=2190cm^2
