Some info about the surface area and volume of the two similar solids has been given. Find the missing value. Solid 1 SA=1088 km2 V=13312 km3 Solid 2 SA= 425 km2 V=?
Let `k` be the scale factor between two objects. If `l_1,A_1` and `V_1` are length, area and volume of one object and `l_2,A_2` and `V_2` are length area and volume of other similar object, then the following formulas hold:
Hence from (2) we get
Now from (3) we get
`V_2=13312/4.096=3250"km"^3` <-- Your solution
