Two similar rectangular prisms have an edge of the proportion of 3:5.
If the smaller prism has a surface area of 69 m.squared, Find the surface area of the bigger prism.
If the bigger prism has a volume of 500 cubic meters, find the volume of the smaller prism.
~~~~~~~~~~~~~~~~
Regarding your first question, multiply the surface area of the smaller cylinder,
which is 69 m^2, by the square of the similarity coefficient, .
multiply the surface area of the smaller cylinder,
which is 69 m^2, by the cube of the similarity coefficient, .

Two similar rectangular prisms have an edge of the proportion of 3:5. If the smaller prism has a surface area of 69 m.squared, Find the surface area of the bigger prism.
----
Surface area is a function of the square of edge lengths ---> 9:25
69*(25/9) = 575/3 sq meters
============================
If the bigger prism has a volume of 500 cubic meters, find the volume of the smaller prism.
----
Volume is a function of the cube of edge length ---> 27:125
500*(27/125) = 108 cubic meters

Ikleyn confused the prism with a cylinder apparently.
