What is the surface area of the cube below? 9 9 9

Natali5045456 [20]

Answer:

$A_s=486\ units^2$

Step-by-step explanation:

Remember that the sides of a cube always have the same length.

In this case the length of the sides L is:

$L = 9$ .

The cubes have 6 faces. Then the surface area of the cube is equal to the area of its 6 faces.

Since all sides of the cube have the same measure, then the area of each face is:

$A = L ^ 2$

Then the area of the 6 faces is:

$A_s = 6L ^ 2$

$A_s = 6 * (9 ^ 2)$

$A_s=486\ units^2$
