Sebuah balok ABCD,EFGH jika luas ABCD =96cm^ , BCGF = 60cm^ dan ABFE = 90cm^ berapakah volume balok tersebu? tolong dengan caranya ya?

Ab= x, bc= y,bf =z persegi panjang abcd=96cm2 ABCD=abxbc 96= abxbc 96= x × y x= 96/y
persegi panjang bcgf = 60 cm2 bc × bf = 60 y × z = 60 z = 60/y persegi panjang abfe= 90 cm2 bf × ab = 90 z × x = 90 60/y x 96/y =90 60 x 96 = 90 × y² 5760/90 = y² 64 = y² √64 = y 8 = y = BC
x = 96/y x = 96/8 x = 12 x = AB = 12
z = 60/y z = 60/8 z= 7,5 z = BF
volume = AB X BC X BF = 12 X 8 X 7,5 = 720 CM³ V = 0,72 LITER/DM³
persegi panjang abcd=96cm2
ABCD=abxbc
96= abxbc
96= x × y
x= 96/y
persegi panjang bcgf = 60 cm2
bc × bf = 60
y × z = 60
z = 60/y
persegi panjang abfe= 90 cm2
bf × ab = 90
z × x = 90
60/y x 96/y =90
60 x 96 = 90 × y²
5760/90 = y²
64 = y²
√64 = y
8 = y = BC
x = 96/y
x = 96/8
x = 12
x = AB = 12
z = 60/y
z = 60/8
z= 7,5
z = BF
volume = AB X BC X BF
= 12 X 8 X 7,5
= 720 CM³
V = 0,72 LITER/DM³
