Crossover Aptitude Test Spatial Reasoning: Odd One Out 4

Question 1

Which object is the odd one out based on the number of faces? A) Cube (6 faces) B) Triangular prism (5 faces) C) Square pyramid (5 faces) D) Pentagonal prism (7 faces)

Accepted Answer

Pentagonal prism (7 faces)

Answer

The cube has 6 faces and the triangular prism and square pyramid each have 5 faces, but the pentagonal prism has 7 faces, making it the odd one out by having the most faces.

Question 2

Four sequences of shapes are shown. Three follow the same rule; one does not. Which is the odd rule? A) Each shape gains one side B) Each shape doubles its sides C) Shapes alternate between curved and straight-sided D) Each shape rotates 45°

Accepted Answer

Each shape doubles its sides

Answer

Adding one side, alternating shape types, and rotating 45° are simple linear or alternating rules, while doubling sides is exponential growth — a fundamentally different rule type.

Question 3

Which is the odd one out in terms of spatial dimensions? A) Area of a rectangle B) Volume of a cylinder C) Surface area of a cube D) Area of a triangle

Accepted Answer

Volume of a cylinder

Answer

Area of a rectangle, surface area of a cube, and area of a triangle are all two-dimensional measures (square units), while volume of a cylinder is a three-dimensional measure (cubic units).

Question 4

Each image shows a set of lines. Which is the odd one out? A) Three parallel horizontal lines B) Three parallel diagonal lines C) Three lines meeting at a single point D) Three parallel vertical lines

Accepted Answer

Three lines meeting at a single point

Answer

Options A, B, and D all show three lines that are parallel to each other (never intersecting), while option C shows three concurrent lines that all meet at one point.

Question 5

Four nets (unfolded 3D shapes) are shown. Three fold into the same type of solid; one does not. The odd net folds into: A) A cube B) A rectangular prism C) A triangular pyramid D) A different cube orientation

Accepted Answer

A triangular pyramid

Answer

A cube, rectangular prism, and different cube orientation are all six-faced box-type solids, while a triangular pyramid (tetrahedron) has only four triangular faces — a fundamentally different solid.
