Answer:
164800
Step-by-step explanation:
to find the total area required of 10 boxes first find of 1 box and then multiply it by 10
Given :
length=20cm
breadth=16cm
height=14cm
total surface area of 1 cuboid is 2(lb+bh+hl)
where l= length and b=breadth and h= height
2(20×16 + 16×14 + 20×14)
20(320+224+280)
20(824)
16480cm^2 = for 1 cuboidical box
for 10 boxes
16480×10
164800cm^2
