AAAAA Cube and Cuboid

January 1, 2024

Answer

No. of diagonals = 16

Explanation

A cube is a three-dimensional shape, that has six square faces of equal dimensions. It has 12 edges and 8 vertices. The primary diagonals of the cube are the straight lines that pass through the centre of the cube and join the opposite vertices. The diagonals of the faces of the cube are the straight lines that join the opposite vertices on each face.

Hence,

Number of primary diagonals of cube = 4
Number of diagonals on the faces of cube = 12
Total diagonals of the cube = 12 + 4 = 16
