Answer:
864 square inches
Step-by-step explanation:
To find surface area, you need to find the area of each face of the cube.
Since all faces of a cube are equal in size, we just need to find the area of one face and multiply it by 6, since there are 6 faces.
So, let's find the area of one of the faces
The length is 12 inches, and since it is a square, the other sides are the same length.
To find the area, we multiply length times width
12 x 12 = 144
Since there are 6 faces, we need to multiply 144 by 6
100 x 6 = 600
40 x 6 = 240
6 x 4 = 24
600 + 240 + 24 = 864
864 square inches
