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?
Answer
A. 81
B. 121
C. 305
D. 405

  • geometry -

    volume ratio is 9^3/11^3
    so, area ratio will be 9^2/11^2
    9^2/11^2 * 605 = 405
