Consider that a b shown on the rectangular prism measures 6 cm. what is the length of the diagonal a f? a) 5 cm b) 7 cm c) 9 cm d) 10 cm

  B)  7 cm

Step-by-step explanation:

The length of diagonal AC satisfies the relation described by the Pythagorean theorem:

  AC² = AB² + BC² = (6 cm)² +(2 cm)² = 40 cm²

The length of diagonal A F also satifies the relation described by the Pythagorean theorem:

  A F² = AC² +CF² = 40 cm² + (3 cm)² = 49 cm²

Then that length can be found by taking the square root of AF²:

  A F = √(AF²) = √(49 cm²)

  A F = 7 cm

c. prove the lengths are the same.

step-by-step explanation:

you need to prove the segments are congruent. congruent segments have the same length. find the lengths of the segments using the distance formula, and compare them.

answer: c. prove the lengths are the same.

-14 is the answer

hope this : ))
