The equation is 54=(n)+(n+1)+(n+2)

Which simplifies to 54=3n+3

Subtract 3 from each side to get 51=3n

Divide each side by 3 to get 17=n

Then you substitute 17 for n to get 17 (n) and 18 (n+1) and 19 (n+2).

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.
