Use the formula sa=6s2 , where sa is the surface area and s is the edge length of the cube, to solve this problem. gavan must paint a cube-shaped box. the edge length of the box is 212 feet. what is the surface area of the box? enter your answer, as a mixed number in simplest form, in the box.

The correct question is
Use the formula SA=6s2 , where SA is the surface area and s is the edge length of the cube, to solve this problem. Gavan must paint a cube-shaped box. The edge length of the box is 2 1/2 feet. What is the surface area of the box?

we know that
[surface area]=6*s²
s is the edge length of the cube

in this problem
s=2 1/2 ft> (2*2+1)/2> 5/2 ft
[surface area]=6*(5/2)²> 6*(25/4)> 75/2 ft²> 37 1/2 ft²

the answer is
37 1/2 ft²

Y=-2x-6 is the answer
