Question

find the surface area of this cube. be sure to include the correct unit in your answer.

Explanation:

Step1: Calculate the area of one face

The area of one face of a cube is \(a\times a\) (where \(a\) is the side length). Here \(a = 4\) ft, so the area of one face is \(4\times4=16\) \(ft^{2}\).

Step2: Multiply by the number of faces

A cube has 6 faces. So the surface area \(S=6\times\) (area of one face). Substituting the value from Step1, we get \(S = 6\times16=96\) \(ft^{2}\).

Answer:

\(96\) \(ft^{2}\)
