do you know the equation to find the surface area for a square pyramid?

Extrinix · Answer

ok, anyways,
so to solve this equation you need to know the formula,
$S=a^2+2al$

now, plug in the numbers,
$S=0.5^2+2(0.5)(0.4)$

solve this and you should have your answer for the `surface area of a square pyramid`
