Question

HELLPPPPPPPPPPPP!!!!!!!!!!!!! I NEED HELP I GOT 1 MIN OR LESS

Answer 1

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

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

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

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

• Surface area of the given square pyramid.

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

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