So, Length \times Breadth = 42Length×Breadth=42
Breadth = \frac{42}{Length}Breadth=
Length
42
Volume of cuboid = length \times Breadth \times Heightlength×Breadth×Height
210=42 \times Height210=42×Height
\frac{210}{42}=Height
42
210
=Height
5=Height5=Height
Total surface area of cuboid = 2(lb+bh+hl)2(lb+bh+hl)
214=2(42+5\frac{42}{l}+5l)214=2(42+5
l

l = 6,7 l=6,7
When length = 6
Breadth = \frac{42}{6}=7Breadth=

=7
When length = 7
Breadth = \frac{42}{7}=6Breadth=

Hence the edges are 6 , 7 and 5
