Question

Find the surface area of the pyramid . The surface area of the pyramid is _m2(Do not round until final answer .Then round to the nearest whole number as needed .)

Answer 1

surface area of the pyramid is

`\begin{gathered} Atotal=Abase+(Pbase\cdot Apothem)/(2) \\ \end{gathered}`

then

`\begin{gathered} \text{Abase}=\frac{P\cdot\text{Apothembase}}{2} \\ \text{Abase}=\frac{18\cdot6\cdot9\sqrt[]{3}}{2}=841.77 \end{gathered}`

and the total area is:

`\text{Atotal}=841.77+(6\cdot18\cdot18)/(2)=841.77+(1944)/(2)=841.77+972=1814`

answer: 1814 m^2
