Question

What is the surface area of a cube with faces that each have an area of 16 cm2?

Answer 1

The cube have 6 faces.
The area of the one face is equal 16 cm².

Therefore:
Surface area of the cube: S=6 × 16 cm² = 96 cm²

Answer 2

To find out what one side measures you will have to take the square root of the Area.


`√(16) =4`

To find out surface area of the cube you use the formula
`A=6 a^(2)`, where a = side.

Therefore,

`A=6 (4^(2))`

`A=6 (16)`

`A=96cm^(2)`
