the volumes of two similar solids are 729m cubic and 125m cubic the surface area of the larger solid is 324m cubic how I can find the surface area of the smaller i nedd the formula
-----------------
There is no formula, you have to figure it out.
--------------------
Volume is a function of the cube of the dimensions.
729 = 9^3
125 = 5^3
The sides are of a ratio 9:5
-----------------
Surface area is a function of the square of the sides.
--> 81:25
The area of the larger is 324, not cubic, sq meters
324 = 4*81
100 = 4*25
--> 100 sq meters for the smaller solid
