Question

AREAS AND VOLUMES OF SIMILAR SOLIDS URGENT?

Answer 1

The ratio between the lengths of similar prisms is

$k=\dfrac{6}{5}$.

If the surface area of small prism is 572 sq. cm, then

$\dfrac{SA_{large}}{SA_{small}} =k^2,\\ \dfrac{SA_{large}}{572} =(\dfrac{6}{5})^2=\dfrac{36}{25} ,\\ SA_{large}=\dfrac{572\cdot 36}{25} =823.68\approx 823,7$ sq. m.

Answer: 823.7 sq. m.
