Answer:
14800 cm²
Step-by-step explanation:
There is no doubt that the box is a cuboid.
In a cuboid if the length is given by L, width is given by W and height is given by H, then the total surface area of the cuboid is given by 2(LW+WH+HL).
Now, it is given that the box is 40 cm. long i.e. L=40 cm, 50 cm wide i.e. W=50 cm. and 60 cm deep i.e. H=60 cm.
Hence the total surface area of the box is 2(40*50+50*60+60*40)
=2(7400)
=14800 cm².
Hence, 14800 cm² area of foil needed for covering the closed box. (Answer)
