If a cube with edges of 1.000 cm weighs 25.68 g, what would the mass of a cube

Question

of the same material with sides 2.66 cm in length be?
I got 68.301 but it was wrong...
i basically made a ratio 25.68 g/1cm and did 2.66cm x 25.68 (dimensional analysis)
This should be very simple but I'm having so much trouble with it. Please help, Thank You!

Answer 1

volume of 2 similar cubes is proportional to the cube of their sides

x/25.68 = 2.66^3/1^3
x = 483.32

Answer 2
