Answer 1

Yes

Explanation:

I think the attached photo is your full question

My answer:

Yes, he can.

Because the base of the rectangular prism is a square, a = b.

After that, we use the Pythagorean Theorem to find out c.

When we have information of c and d, once again use the Pythagorean Theorem to find out x.
