Luas alas
P x L
karena masih perbandingan, berikan simbol X
96= 3X x 2X
96= 6X kuadrat
16= X kuadrat
4= X
masukkan ke masing masing
P= 3x4=12
L= 2X4=8
T=1X4=4
Volume= PLT
12X8X4
384 Cm kubik
p=3x
l=2x
t=x
luas alas = p × l
96 = (3x)(2x)
96 = 6x²
96:6 = x²
√16 = x
4 = x
maka diperoleh
panjang = 3x =3(4)=12 cm
lebar = 2x = 2(4)= 8 cm
tinggi = x = 4 cm
volume balok
=p × l × t
=12 × 8 × 4
=384 cm³
