Question

AREAS AND VOLUMES OF SIMILAR SOLIDS URGENT?

Answer 1

The ratio between the lengths of similar prisms is

`k=(6)/(5)`.

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

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

Answer: 823.7 sq. m.
