Question

ALGEBRA! NEED HELP!
~Write a formula for the total surface area of a cube in terms of its edge length x. Explain your reasoning.

Answer 1

Since each edge's length is x, each face's are would be ${ x }^{ 2 }$
And cubes have 6 faces. multiply 6 by ${ x }^{ 2 }$, the formula is :$6{ x }^{ 2 }$

Answer 2

surface area of a cube
cube=6 squares
square=2 equal sides
area of square=side^2
surface area of cube=6(area of square)=6side^2
side=x
SA=6x^2
