Question

Which of the following is not a classical impossible constructions of geometry?

• A. Trisecting an angle
• B. Squaring a circle
• C. Doubling a Cube
• D. Sphere having $8$ times the volume

Answer 1

The correct option is D Sphere having $8$ times the volume

The 3 classical impossible constructions of Geometry are:
a. Trisecting an angle
b. Squaring a circle
c. Doubling a cube

Sphere having $8$ times the volume is not a classical impossible construction of geometry as it is possible.

$\therefore$ Sphere having $8$ times the volume among the given options is not a classical impossible construction of Geometry.
