Question

Find the surface area of the figure. Round your answer to the nearest hundredth.

$311.4 {ft}^{2}$
$155.7 {ft}^{2}$
$196.2 {ft}^{2}$
$248.4 {ft}^{2}$

hint Hint:

The surface area of Pyramid = where p is the perimeter of the base , B is area of the base and l is the slant height of the pyramid.

The correct answer is: $311.4 ft squared$

Given , the base of the pyramid is square of side length 9 ft and slant height of pyramid is 12.8 ft $text The perimeter of square base is 4 x 9 = 36 ft end text text The area of the square base is end text 9 squared equals 81 space ft squared U s e space t h e space s u r f a c e space a r e a space f o r m u l a comma space S u r f a c e space a r e a space equals space B space plus 1 half space cross times space P l S. A space equals space 81 space plus space 1 half left parenthesis 36 right parenthesis left parenthesis 12.8 right parenthesis equals 311.4 space ft squared$
Therefore, the surface area of the pyramid is $311.4 ft squared$
