RUMUS-RUMUS =

Luas permukaan

$Description: L = 2\cdot (p\cdot l + p\cdot t + l\cdot t)$

Volume

$Description: V = p\cdot l \cdot t$

Panjang diagonal ruang

$Description: d_R = \sqrt{(s^2+s^2+s^2)}$

Panjang diagonal bidang

$Description: d_{B1} = \sqrt{(s^2+s^2)}$
$Description: d_{B2} = \sqrt{(s^2+s^2)}$
$Description: d_{B3} = \sqrt{(s^2+s^2)}$

Luas bidang diagonal

$Description: L_{B2} = d_{B2}\cdot l$

RUMUS-RUMUS =

Luas permukaan

Luas permukaan limas dengan alas segi-n dapat dihitung dengan rumus berikut:
L = a + (n.t)
Catatan: yang diambil salah satu sisi tegaknya saja.

Volume

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