1223.65 {in}^{2} [/tex]

Step-by-step explanation:

[tex]surface area of a pyramid\\ = lw + l( \sqrt{ \frac{w}{2} ) ^{2} + {h}^{2} + w } \sqrt{ (\frac{l}{2}) ^{2} + {h}^{2} } \\ =

20

·

20

+

20

· \sqrt{ {( \frac{20}{2} )}^{2} + {18}^{2} + 20} \times \sqrt{ { (\frac{20}{2}) }^{2} + {18}^{2} } \\ ≈

1223.65041
