Answer 1

Answer:

l =5 m

b=4m

h=3m

diagonal of cubiod gives the length of the longest bamboo stick

diagonal of cubiod = root of l^2 + b^2 + h^2

=root of (5^2 + 4^2 + 3^2)

=root of 25+ 16+ 9

= root of 50

or

5*root 2

that should be ur ans

hope it helps!!

Answer 2

60 m

Step-by-step explanation:

The length of longest bamboo stick is

l*b*h= m
