For more than two thousand years, the Doubling of the Cube—the construction of the cube root of two using only a compass and straightedge—has stood as one of classical geometry's greatest impossibilities. Declared unsolvable by algebraic proof, it became a symbol of mathematical limitation.

In ***The Construction of Cube Root (An Addition in Euclidean Geometry)***, Manoranjan Ghoshal challenges this long-accepted conclusion.

n

Blending historical insight with original geometric reasoning, the author revisits the foundations of Euclidean construction and introduces a new theorem that leads to a step-by-step geometric method for extracting cube roots using classical tools. The book carefully explains the logic, construction process, and implications, making a complex idea accessible to students, teachers, and independent researchers.

n

Written in lucid language and supported by clear geometric reasoning, this work invites readers to rethink impossibility, question tradition, and explore geometry beyond established boundaries.

n

A bold contribution to classical geometry—provocative, educational, and thought-inspiring.
