<u>Answer;</u>

  = 1,872 sq inches

<u>Explanation;</u>

The surface are of a rectangular prism is the sum of the areas of all the faces.

The area of a rectangular prism is given by the formula;

A=2(wl+hl+hw), where w is the width, l the length and h is the height;

Thus; A = 2( (24× 18) + (12×18) + (12× 24)

             = 2 ( 432 + 216 + 288 )

             = 2 × 936

             = 1,872 sq inches
