A stairway with three steps has three risers that are each 8 inches high and three treads that are each 10 inches deep. What is the area, in square inches, of this figure that is the side panel of the stairway?

Don't see  a figure, but I believe that we have three rectangles,  each with a height of 8 inches and a width of 10 inches....so the total area of the side panel is

 

3 * (8 *10)  =

 

3 * 80  =

 

240 square inches
