Mari pushed a box that is a cube. it fell off the table. does a face of the box have a right angle? explain how you know

Every face of a cube has 4 right angles.

A cube is defined as a three dimensional shape whose faces are all squares.  A square is a quadrilateral in which all sides are equal and all angles are 90°.

This is what i found “an explicit formula designates the nth term of the sequence, as an expression of n (where n = the term's location). it defines the sequence as a formula in terms of n. this example is an arithmetic sequence(the same number, 5, is added to each term to get to the next term).” i hope this you for what your looking for. can you plz mark me brainliest?
