A surface area of a cube is related to its volume V by A = 6. V(2/3). If the volume of a
Luda [366]

The surface area of the cube is 64 cm².

<h3 /><h3>What is volume?</h3>

Volume is the amount of space that is enclosed within a container.

To calculate the surface area of the cube, we use the relation below.

Formula:

  • A = 6V{2/3}............ Equation 1

Where:

  • A = Surface area of the cube
  • V = Volume of the cube.

From the question,

Given:

  • V = 35 cm³

Substitute this value into equation 1

  • A = 6(35){2/3}
  • A = 6(10.6999)
  • A = 64.2
  • A = 64 cm²

Hence, The surface area of the cube is 64 cm².
