Question

If the lateral surface area of a cube is 144 cm^2, then its volume is​

Answer 1

Answer:

864 cm2

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
