Total surface area = 216 cm²

Let the side of the cube = a

Thus 6a² = 216

⇒ a² = 216/6

⇒ a² = 36

⇒ a = √36

⇒ a = 6 cm

Volume = a³ cm³ = 6³ cm³ =

Let the side of the cube = a

Thus 6a² = 216

⇒ a² = 216/6

⇒ a² = 36

⇒ a = √36

⇒ a = 6 cm

Volume = a³ cm³ = 6³ cm³ =

**216 cm³**we know that

t.s.a of cube is 6a²

but from the problem is 216cm²

so, 6a²=216

=> a²=216/6

=>a²=36

=> a=6

therefore side of the given cube is 6cm

therefore volume of cube is a³ =6³ =216
