Answer: 17.29 cm
Step-by-step explanation:
Given
The dimension of a rectangular prism is [tex]13\ cm\times 9\times \ cm\times 7\ cm[/tex]
The longest line which can be drawn in the rectangular prism is diagonal across the body which is shown in the figure
Length of rectangular is given by
[tex]\Rightarrow L=\sqrt{l^2+b^2+h^2}[/tex]
Putting values
[tex]\Rightarrow L=\sqrt{13^2+9^2+7^2}\\\Rightarrow L\sqrt{169+81+49}=\sqrt{299}\\\Rightarrow L=17.29\ cm[/tex]

17.3
Step-by-step explanation:
The dimension of a rectangular prism is 13x9x7
