Question

Surface area of a cube if the sides are 0.7

Answer 1

`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
`s` 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`
