volume balok = 3.780 cm3
panjang x lebar x tinggi = 3.780
(16 + x) (23 - x) 10 = 3.780
(16 + x) (23 - x) = 378
368 - 16x + 23x - x² = 378
368 + 7x - x² - 378 = 0
-x² + 7x - 10 = 0
-------------------------x (-1)
x² - 7x + 10 = 0
(x - 2) (x - 5) = 0
x = 2 / x = 5
Jadi nilai x adalah 5 cm
moga membanttuu
