To find the surface area of the whole cube, you need to first find the area of one side.
So one side is just a square with length and width of 7mm. So the area would be 7 x 7 = 49mm². 
Since there are 6 sides on a cube, multiply this area by 6 to give you the whole surface area of the cube.
49 x 6 = 294mm²

The surface area A of a cube is equal to the sum on the areas of the 6 square faces that form the cube. If each face has side le
algol [13]

Answer:

18 units

Step-by-step explanation:

Hello, I can help you with this.

Step 1

identify

we have a equation, let's look  it

A=6s2

The surface area A of a cube=6(area of a face)

area of face= side*side

so

Area=6*side*side

Step 2

isolate side from the equation

side^{2}=\frac{Area}{6}\\side=+\sqrt{\frac{Area}{6}}

we are looking for a distance, so , we will use only the positive root

Step 3

replace the value of 1944 square units into the equation

side=+\sqrt{\frac{Area}{6}}\\side=+\sqrt{\frac{1944}{6}}\\side=\sqrt{324}\\\\side=18\\

so, the value x of a side of a cube with a total

the side of a cube is 18 units  when the surface area of the cube shown is 1944 units2

Have a good day.
