$\sf\large\underline{\star Given:-}$

$\rightarrow$ Measure of its each edge =
$\sf\red{8feet.}$

$\rightarrow$ Height of each lateral surface (or slant height) =
$\sf\red{15feet.}$

$\sf\large\underline{\star To\: Find:-}$

$\sf\large\underline{\star Formula \:Used:-}$

$\rightarrow$ Surface Area of square pyramid =
$\sf\blue{a^2+2al}$

Where,

$\sf\pink{a^2}$
$\sf{=\: Area \: of\: base.}$

$\sf\pink{a}$
$\sf{=\: Side \:of \:the\: base.}$

$\sf\pink{l}$
$\sf{=\: Slant \:height}$

$\sf\large\underline{\star Solution:-}$

$\rightarrow$ Surface Area of square pyramid =
$\sf{a^2+2al}$ (putting the value of
$\sf{a^2}$ , a and l)

$\rightarrow$
$\sf{=\: 8^2+2(8×15)}$

$\rightarrow$
$\sf{=\: 304feet^2}$

Therefore, surface area of the given square pyramid
$\sf\purple{=\: 304feet^2.}$
