To find the surface area of the rectangular prism the area of all the sides must be found and added together.
The formula for the surface area of a rectangular prism can be expressed as:
where
= length
= height
= width
Before plugging in the values in the equation the length of the prism must be converted to inches
1 ft. = 12 in.
Therefore 2 ft. = 24 in.
By plugging in the values of length, width, and height into the equation
2(24)(14) + 2(24)(11) + 2(14)(11) = 1508 in.²
