Answer:
150 square inches
Step-by-step explanation:
The surface area of the cube is
[tex]S_A=A_1+A_2+A_3+A_4+A_5+A_6[/tex]
but it's a cube so all the areas are the same
[tex]S_A=6A_1[/tex]
and the area of
[tex]A_1=l^2[/tex]
[tex]l=5\\\\A_1=5^2\\\\A_1=25[/tex]
so the surface area is
[tex]S_A=6(25)\\\\S_A=150[/tex]square inches
