Answer:
9.21ft
Explanation:
Given data
L= 6ft
W= 8ft
H= 7ft
Let us find the diagonal of the side, this represents the longest size of pipe the box can take
z^2= L^2+ H^2
z^2= 6^2+ 7^2
z^2= 36+49
z^2= 85
z= √85
z= 9.21ft
Hence the 12ft cannot fit into the box
the length of pip that can fit is 9.21ft
