the shapes shown are different cross - sections of the same three - dimensional object. which three - dimensional object has these cross - sections?
Answer
Explanation:
Step1: Analyze cross - section of cone
A cone's cross - sections are a circle (parallel to base), an isosceles triangle (vertical cross - section through the vertex), and not rectangles. So option A is incorrect.
Step2: Analyze cross - section of cube
A cube can have a square cross - section (parallel to a face), a rectangle (when cut at an angle to a face), and a triangle (when cut through three non - parallel edges). This matches the given cross - sections.
Step3: Analyze cross - section of cylinder
A cylinder's cross - sections are a circle (parallel to base) and a rectangle (vertical cross - section), but not a triangle. So option C is incorrect.
Step4: Analyze cross - section of triangular pyramid
A triangular pyramid's cross - sections are triangles and sometimes trapezoids, but not rectangles in the general sense as given here. So option D is incorrect.
Answer:
B. Cube
