tinggal satu lagi nih

Keliling persegi = 4 x s
sisi alas limas (persergi)= 72 : 4
                                      = 18 cm

a. tinggi limas = b = √c² - a²
                             = √15² - (18 : 2)²
                             = √144
                             = 12 cm tinggi limas

b. Volume limas = 1/3 x (s x s) x t
                          = 1/3 x (18 x 18) x 12
                          = 1296 cm

A.panjang alas limas
=72 cm /4
=18cm

.tinggi limas
=15² - (18/2)²
=225 - 81
=√144
=12 cm


B.Volume limas
=1/3 x 18cm x 18cm x 12 cm
=1.296 cm³


Tolong jadiin jawaban terbaik ya!!!
