aksik [14]

<h2>The surface area of the cube is 0.375 square units.</h2>

Step-by-step explanation:

Given : The formula for the surface area of a cube is $SA=6s^2$ , where s is the length of one side of the cube if $s=\frac{1}{4}$ of a unit.

To find : What is the surface area, in square units, of the cube?

Solution :

The formula for the surface area of a cube is $SA=6s^2$

We have given, $s=\frac{1}{4}$

Substitute in the formula,

$SA=6(\frac{1}{4})^2$

$SA=6\times \frac{1}{16}$

$SA= \frac{3}{8}$

$SA=0.375$ square units.

Therefore, the surface area of the cube is 0.375 square units.
