To find the length of the diagonal of the rectangular prism, we can use the formula for the space diagonal of a rectangular prism:

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

where:

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

Given:

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

Let's calculate the diagonal:

\[ d = \sqrt{32^2 + 24^2 + 44^2} \]

Calculating each term:

\[ 32^2 = 1024 \] \[ 24^2 = 576 \] \[ 44^2 = 1936 \]

Now, sum these values:

\[ 1024 + 576 + 1936 = 3536 \]

Now, take the square root of 3536:

\[ d = \sqrt{3536} \approx 59.5 , \text{cm} \]

Therefore, the length of the diagonal of the rectangular prism, segment \( BE \), is approximately \( 59.5 , \text{cm} \).

Final answer: 59.5 cm
