Question

The volume of two similar solids is 1331 m3 and 729 m3. The surface area of the larger solid is 605 m2.

What is the surface area, in square meters, of the smaller solid?
Explanation and answer please or just answer :)

Answer 1

81
121
305
405

Answer 2

305?

Answer 3

cubert 1331 / cubert 729 gives ratio of corresponding lengths of similar objects

the surface areas will be in ratio of squares of the above values

Answer 4

cubert 1331 = 11 and of 729 = 9 ratio of 11:9
so areas
will be in ratio
121 : 81

Answer 5

so
121/81 = 605/ x

find x

Answer 6

405? and that's the answer?
