To find the length of the diagonal of the rectangular prism (segment BE), we can use the formula for the diagonal \(D\) of a rectangular prism, which is given by:

\[ D = \sqrt{l^2 + w^2 + h^2} \]

where:

  • \(l\) is the length,
  • \(w\) is the width,
  • \(h\) is the height.

In this case:

  • Length \(l = 32 , \text{cm}\)
  • Width \(w = 24 , \text{cm}\)
  • Height \(h = 44 , \text{cm}\)

Substituting these values into the formula:

\[ D = \sqrt{32^2 + 24^2 + 44^2} \] \[ = \sqrt{1024 + 576 + 1936} \] \[ = \sqrt{3536} \]

Now, we calculate the square root:

\[ D \approx 59.5 , \text{cm} \]

Thus, the length of the diagonal of the rectangular prism (segment BE) is approximately 59.5 cm.
