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.
