Class 8 Mathematics — Cubes and Cube Roots Important Questions with Answers (Long answers)
Class 8 Mathematics is the last middle-school year before Class 9 polynomials and Euclid. Rational numbers get a full number-line treatment, linear equations move beyond one-step, and mensuration adds cubes and cylinders. This bank follows the rationalized NCERT so you are not revising deleted chapters. Search terms such as “class 8 rational numbers important questions” and “linear equations class 8 MCQ” open the matching chip. Twenty questions a page, answers folded.
Hardy’s taxi 1729 is optional folklore; unit-digit patterns and prime-factor cube roots are the marks. A perfect cube has exponents that are multiples of 3 in prime factorisation. Cube of a negative is negative. Keep that sign when the paper asks ∛(−125). You are on Cubes and Cube Roots (Long answers), page 1 of 1 — 2 questions in this filter. Long answers model a five-mark write-up: definition, reason, one diagram or equation idea, and a closing line. Do not copy the whole block in the exam; steal the order. This view is for the night before a unit test. Phone layout: chapter chips scroll sideways, answers stay inside a tap, and the next page is a numbered link so Google and students both get a short URL. Updated for 2026 classroom practice on the rationalized NCERT.
