Answer:

<h2>823.7 m²</h2>

Step-by-step explanation:

If a figure A and a figure B are similar, then

\dfrac{area_A}{area_B}=k^2    (*)

<em>k</em><em> - similarity scale</em>

<em />

Calculate the similarity scale:

k=\dfrac{6}{5}

We have the surface area of the smaller prism 572 m².

Substitute to the formula (*):

\dfrac{x}{572}=\left(\dfrac{6}{5}\right)^2\\\\\dfrac{x}{572}=\dfrac{36}{25}\qquad\text{cross multiply}\\\\25x=(36)(572)\\\\25x=20,592\qquad\text{divide both sides by 25}\\\\x=823.68\approx823.7\ m^2
