Misalsisi alas balok = s
tinggi balok = t
karena alas balok berbentuk persegi,
maka
luas balok = 96cm²
2×s² + 4st = 96
s² + 2st = 48
t = ( 48 - s² )/2s
volume balok = s² × t
V = s² * ( 48 - s² )/2s
V = 24s - ½s³
agar V maks, maka V ' = 0
24 - 3/2s² = 0
s² = 16
s = 4 cm
maka volume balok terbesarnya = s³ = 4³ = 64cm³ ✔️
semoga jelas dan membantu
