alleryWhich condition makes a rectangular cuboid a regular polyhedron?
AIts three dimensions are all different
BOnly its opposite faces are congruent
COnly its lateral faces are rectangles
DIts length, width and height are equal
Answer & Solution
Correct answer: D. Its length, width and height are equal
Equal length, width and height make a cube with congruent regular square faces and equal face incidence at every vertex.
