The surface area of the rectangular prism is approximately 5.32 square feet.
A rectangular prism is simply a polyhedron with two congruent and parallel bases.
The surface area of a rectangular prism is expressed as:
Surface area = 2 ( wl + hl + hw )
Where l is the length, w is the width and h is the height.
Given that:
Length l = 13 inches
Width w = 10 inches
Height h = 11 inches
Surface area =?
Plug the given values into the above formula and solve for the surface area:
Surface area = 2( wl + hl + hw )
Surface area = 2( 10×13 + 11×13 + 11×10 )
Simplifying, we get:
Surface area = 2( 130 + 143 + 110 )
Surface area = 2( 383 )
Surface area = 766 square inches
Convert to square feet:
Surface area = 766/144
Surface area = 5.32 square feet
Therefore, the surface area measures 5.32 square feet.
