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

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!
