Here you are the
Surface Area of a Rectangular Prism = 2ab + 2bc + 2ac (a, b, and c are the lengths of the 3 sides)
In words, the surface area of a rectangular prism is the area of the six rectangles that cover it. But we don't have to figure out all six because we know that the top and bottom are the same, the front and back are the same, and the left and right sides are the same.
The area of the top and bottom (side lengths a and c) = a*c. Since there are two of them, you get 2ac. The front and back have side lengths of b and c. The area of one of them is b*c, and there are two of them, so the surface area of those two is 2bc. The left and right side have side lengths of a and b, so the surface area of one of them is a*b. Again, there are two of them, so their combined surface area is 2ab.

Step-by-step explanation:
it's an exponential function
The display after stacking of 6 layers of cube is 30 inches high.
Step-by-step explanation:
The volume of cubic box used by Abbey= 125 inch³
Total no of layer he has in display= 6
Height of the display-
We know that the volume of the cube is a³
Where a is the side of the cube
Hence to find the side of the cubic box we need to find the cube root of the volume i.e. ∛125
Hence the side of each cube is 5 inch. Since all the sides for cube are equal hence the height would also be 5 inch
The total height of the display would be 6*5= 30 inches
