Limas iku wangun kaya déné piramid (mbrujung mandhuwur). Asring ana ing pambelajaran ilmu étung utawa matématika. Ing geometri, limas yaiku wangun telung dimènsi kang dibatesi wangun kang awujud segi-n lan sisi-sisi tegak wujudé segitelu.

Wangun Kerucut bisa kagolong ing limas kanthi dasar wujudé bunder lingkaran.

Limas kanthi dasar yaiku pesagi bisa uga kasebut piramida.

The 1-skeleton of pyramid is a wheel graph

Rumus limas

Jembar permukaan

Jembar permukaan limas lan alas segi-n bisa dietung kanthi rumus, thuladha d:
$L = a + (n . t)$

Tetrahedron	Square pyramid	Pentagonal pyramid

Volume

$V = \frac{1}{3}\cdot Luas Alas \cdot t$
