The length of the diagonal shown in the rectangular prism is; 9.5 ft
First of all, we have to find the length of the diagonal base to get;
x = √(4² + 7²)
x = √65
Thus;
Length of the diagonal shown = √(5² + (√65)²)
Length of the diagonal shown = √90
Length of diagonal shown = 9.4868
Length of diagonal shown ≈ 9.5 ft
