mencari panjang sisi
AC adalah diagonal
diagonal = s√2
4√2 = s√2
s = 4 cm
mencari tinggi Limas
= √4^2 - (2√2)^2
= √16 - 8
= √8
= 2√2
volume Limas
= 1/3 . luas alas. t
= 1/3 . 4 . 4 . 2√2
= 15
maka sisinya=4 cm
sisi tegak lurus= 4cm
jadi tingginya sama dengan=2√2
v=1/3.La.t
=1/3.4.4.2√2
=1/3.16.2√2
=1/3.32√2
=15 cm
