Answer:
989 in^2
Explanation:
The surface area of the larger cube is
SA = 5 s^2 because she will stain all the sides but the bottom one
SA = 5 * 11^2 = 5*121 = 605
The surface area of the smaller cube is
SA = 6s^2 since she will stain all sides
SA = 6* 8^2 =6*64 =384
Add both surface areas together
605+384
989
