Question

If the volume of cube is 27cm³,find its total surface area​

Answer 1

Explanation:

We have to find the side of the cube.

Volume of cube = 27 cubic cm

`side^(3)=27 = 3^(3)\\\\Both \ sides \ take \ cube \ root\\\\\sqrt[3]{side^(3)}=\sqrt[3]{3*3*3}\\\\side = 3 \ cm \\`

Area of cube = 6*side²

= 6 * 3 * 3

= 54 cm²
