Answer:
864 cm 2
Step-by-step explanation:
Let each side of the cube be a cm.
Then, the lateral surface area of the cube = 4a2
∴ 4a2 = 576 ⇒ a2 = 576/4 cm2 = 144 cm2 ⇒ a = 12 cm
Volume of the cube = a3 = (12 cm)3 = 1728 cm3
Total surface area of the cube = 6a2 = 6 x 122 = 864 cm2
Answer:
12
Step-by-step explanation:
576 = 4( side)^2
576/4 = side^2
144 = side^2
√144 = side
12 = side
