What is cubism and tell me the meaning of it

Cubism is a style of art, begun in the early twentieth century, in which objects are represented as if they could be seen from several different positions at the same time, using many lines and geometric shapes.

An accurate definition, as found on Google states that,

Cubism is an early-20th-century art movement which brought European painting and sculpture historically forward toward 20th century Modern art. Cubism in its various forms inspired related movements in literature and architecture.
