•Volume kubus•
S = 5cm
V = s³
= 5 x 5 x 5
= 125
•Luas permukaan kubus•
S = 5 cm
L = 6x s²
= 6 x 5 x 5
= 6 x 25
= 150 cm
jadi volume kubus = 125 cm
luas permukaan kubus = 150 cm
•Volume Balok•
V = p x l x t
= 10 x 2 x 6
= 120 cm
•Luas permukaan balok•
L = 2( pl + pt + lt )
= 2 x ( 10 x 2) + ( 10 x 6 ) + ( 2 x 6)
= 2 x ( 20 + 60 + 12 )
= 2 x 92
= 184 cm
jadi volume balok = 120 cm
luas permukaan balok = 184 cm

semoga membantu
