**Reiny**, Sunday, March 16, 2014 at 7:19pmvolume of 2 similar solids is proportional to the cube of their corresponding sides, so

x/240 = 23^3/92^3 = (23/92)^3 = (1/4)^3 = 1/64

64x = 240

x = 3.75

the new volume is 3.75 ft^3

If I told you that the surface area of 2 similar solids is proportional to the square of their corresponding sides, can you set it up like I just did ?

let me know what you got.
