Answer:
Option D) The volumes of the boxes are the same.
Step-by-step explanation:
Given that Rhea has two cardboard boxes in the shape of rectangular prisms. Each box has the same height and cross-sectional area as the other.
Since we are given height and cross sectional area are the same, we see that the bases have same area. The dimensions need not be congruent.
Hence the boxes need not be congruent
Surface area also need not be congruent since length, width may differ for each prism
The area is the same need not imply perimeter is the same.
Hence only option d) The volumes of the boxes are the same.
is the right answer.

Answer:
-2/5
Step-by-step explanation:
When you reflect a point across the line y = x, the x-coordinate and y-coordinate change places. If you reflect over the line y = -x, the x-coordinate and y-coordinate change places and are negated (the signs are changed). the line y = x is the point (y, x). the line y = -x is the point (-y, -x).
