Question

Mary wants to decorate her Christmas tree. She wants to place the tree on a

wooden box covered with coloured paper with picture of Santa Claus on it. She

must know the exact quantity of paper to buy for this purpose. If the box has length,

breadth and height as 80 cm, 40 cm and 20 cm respectively how many square

sheets of paper of side 40 cm would she require?​

Answer 1

Step-by-step explanation:

Lenght-80cm

Breadth-40cm

Height-20cm

We have to find the area of CUBOIDAL box

-Area of CUBOID-2(lb+bh+hl)

PUT THE VALUES IN THE FORMULA

=2(80×40+40×20+20×80)

=2(3200+800+1600)

=2(5600)

=11,200 cm sq

Therefore Area of box =11,200cm sq

NOW WE WILL FIND THE SHEETS REQUIRED

Square sheets required= Area of box÷square sheets of 40cm

=11,200÷40

=280 SHEETS

THEREFORE SHEETS REQUIRED ARE 280.

280 sheets is answer dear friend
