The surface area of a cube can be found using the formula S = 6e. If a cube
has an edge of 3.5, what is the surface area of the cube?

Respuesta :

Answer:

S = 73.5 unit³

Step-by-step explanation:

[tex]A_{s} = 6e^{2}[/tex]

[tex]A_{s} = 6 (3.5)^{2}[/tex]

[tex]A_{s} = 6 (12.25)[/tex]

[tex]A_{s} = 73.5[/tex]

Answer:

73.5 unit^2.

Step-by-step explanation:

Area =  e^2

Area of one face = 3.5^2 = 12.25 unit^2.

So total surface area = 6 * 12.25

= 73.5 unit^2.
