A cube is a three-dimensional (3D) solid object in geometry. It is one of the five Platonic solids and is highly symmetrical. The most defining characteristic of a cube lies in its faces.
A standard playing die is a perfect example of a cube.
A cube is a special type of rectangular prism (cuboid) where all sides are equal.
The diagonal of a cube can be calculated as a√3.
The statement is: All six faces of a cube are identical squares.
Because every face is a square, every face has the exact same area, and every single edge (side) of the cube is of the exact same length. The angles between any two intersecting faces are always exactly 90 degrees (right angles).
Exactly three faces meet at each vertex (corner) of a cube.
Euclid's Division Lemma — Statement and Examples
Learn Euclid's Division Lemma for Class 10 Maths. Statement: a = bq + r. Understand how it is used to find the HCF of two numbers with solved examples.
Evaluate 101 × 99 Using Algebraic Identity
101 × 99 = 9999. Using identity (a+b)(a-b) = a²−b²: (100+1)(100−1) = 100²−1² = 10000−1 = 9999. Step-by-step solution.
Evaluate 501 × 501 Without Actual Multiplication — Using Algebraic Identity
501 × 501 = 251001. Solve using (a+b)² = a² + 2ab + b² identity where a=500, b=1. Learn the method with more examples and FAQs.
