Answer:
Given:
l= 80 cm , b = 40 cm, h=20 cm
Side of a square sheet= 40 cm
Wooden box is in the shape of cuboid.
Surface area of the box = 2(lb+bh+hl)
= 2( 80×40 + 40×20 + 20×80)
= 2(3200+800+1600)
=2(5600)
= 11200 cm²
Surface Area of the box= 11200 cm²
Area of 1 sheet =area of square= side ×side
Area of 1 square sheet = 40 cm × 40 cm =1600 cm²
Number of square sheets required =surface area of box/ area of 1 square sheet
= 11200/1600=7
Hence,she would require 7 Square sheets.
HOPE THIS WILL HELP YOU....
