Answer 1

Penjelasan dengan langkah-langkah:

ac = 15 cm

ab = 9 cm

fc = 20 cm

• cari panjang bc

= √(ac² - ab²)

= √(15² - 9²)

= √(225 - 81)

= √144

= 12 cm

• volume

= La x t

= (a x t : 2) x t

= (9 x 12 : 2) x 20

= 54 x 20

= 1.080 cm³

Answer 2

BC :

= √15² - 9²

= √(15(15) - (9(9)

= √225 - 81

= √144

= √12²

= 12 CM

MAKA :

V = (9(12)/2)(20)

= (108/2(20)

= (108(20)/2

= 2.160/2

= 1.080 CM³
