Answer:

Step-by-step explanation:

:P  nice points ty :)

find the length of the long diagonal across the tank.  

first find the 2D  diagonal , then use that dist. to find the long 3D diagonal

[tex]C^{2}[/tex] = [tex]3^{2}[/tex]+[tex]4^{2}[/tex]

C = 5    (2D)

now find the 3D

[tex]C^{2}[/tex] = [tex]5^{2}[/tex]+[tex]12^{2}[/tex]

C = 13  inches

( they made it easy ) :)
