The surface area of the book is 246.2 inches².
Since all the components to solve the equation are already present, you can utilize a surface area formula for a rectangular prism.
l = length, w = width, h = height
Surface area formula for a rectangular prism: (2lw + 2wh + 2hl).
(2 x 10.4 x 2) = 41.6 inches²
(2 x 2 x 8.25) = 33 inches²
(2 x 8.25 x 10.4) = 171.6 inches²
You then add all these components together to get the total surface area.
(41.6 + 33 + 171.6) = 246.2 inches²
Hope this helps!
