.
For your info:
(1) Pyramids do not have sides.
They have FACES, EDGES and VERTICES.
(2) To solve the problem correctly, we need to know, which of the two given
edges is the side of the base square and which is the lateral edge.

For what reason do you need the solution, when you do not know terminology ?
Learn terminology first.
On volume of pyramids, see the lessons in this site

If you will need more lessons on surface area or volume of solids, let me know.
I will give you many other relevant links to my lessons.
Happy learning (!)

@MathLover1 starts her solution hypothesizing that
“Two of the sides” means side of the base and is slant height .
This hypothesis VERY EASY can be wrong / irrelevant, and the slant height is NEVER considered as a "side".
So be careful if her solution is applicable.
In Math, serious teachers/tutors DO NOT MAKE such hypotheses, when teach the student.
A serious tutor REQUESTS the student to provide a RELIABLE input.
