Answer: 290 inches squared.
Explanation:
The surface area of a solid object is a measure of the total area that the surface of the object occupies.
The surface area for two faces of the rectangular prism is given.
The first one is a square, with a given area of 25 inches squared. The second one is a rectangle with a given area of 60 inches squared.
We know that each rectangle has the same side length and width, meaning that each rectangle has the same area. And since there are 4 rectangles with the same area, we can multiply its area of 60 inches squared by 4, getting the number 240.
The same rule applies to the squares, as there are two squares, we can multiply 25 by 2, and get 50.
Lastly we need to add up the total areas to get the whole surface area, which is 50 + 240 = 290 inches squared.
