A:
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
