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

Sagot :

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

[tex] \sqrt{16} =4[/tex]

To find out surface area of the cube you use the formula [tex]A=6 a^{2}[/tex], where a = side.

Therefore,
[tex]A=6 (4^{2})[/tex]
[tex]A=6 (16)[/tex]
[tex]A=96cm^{2}[/tex]
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
