Mencari volume limas jika di ketahui rusk 14 cm dan tinggi 6 cm

V limas = 1/3 x 14 x 6
= 28 cm(pangkat tiga)

jari-jari lemas = akar { (14)^2 - (6)^2 }
= akar (196 - 36)
= akar 160
volume limas = 1/3 ( luas alas x tinggi )
= 1/3 ( phi.r^2.t)
= 1/3 { 22/7.(akar 160)^2.6 )
= 1/3 ( 22/7.160.6)
= 2( 22/7.160)
= 1.005 5/7 cm^3
