Answer:

$SA = 2.94 \, \textrm{units}^2$

Explanation:

The surface area of a regular 3D figure can be represented as:

$SA = A_{\textrm{\,1 side}} \cdot (\# \textrm{ of sides})$ .

Therefore, the surface area of a cube is:

$SA = s^2 \cdot 6$

where
is the length of a side.

To solve this problem, simply input the given side length into the above formula:

$SA = 0.7^2 \cdot 6$

and simplify.

$SA = 0.49 \cdot 6$

$SA = 2.94 \, \textrm{units}^2$
