The figure below is a right rectangular prism.
A rectangular prism is shown. Rectangles S M T Z and X N O Y are the bases. The length of W M is x and the length of M T is x. The height of the prism is one-half x.
Which expression represents the volume of the prism?
One-halfx3
(one-half x) cubed

m∠5 + m∠3 = m∠1   is true.

m∠5 + m∠6 = 180 is true

m∠2 +m∠3 = m∠6   is true

m∠2 +m∠3 +m∠5 = 180   is true

dont't really have enough info here but its likely

sss for the three sides being congruent ( its stands for side side side)

or

sas   for side angle side.   so a side is congruent and and angle and a side
