Answer:
150
Step-by-step explanation:
The problem is asking for surface area. When you are looking for surface area of a cube, you want to find the area of each face and then add everything together.
Here, we're given that one side is 5 inches. We can multiply 5 x 5 to get the area of one face, 25 inches. A cube has six faces, so in order to get the surface area of the entire cube, we multiply 25 x 6. That's the same as adding 25 six times. The product is 150.
