I am thinking of a number. I subtract 10 then divide by 2 and I now have 19. What was my original number? (Hint: Start with the

number at the end, 19, and work in "reverse". In other words, 19 × 2 + 10.)

I really need help with this question!

Same as all the other ones like this.

Since the two figures are similar . . .

-- The ratio of of their volumes is  R³ .

-- The ratio of their surface areas is  R² .

-- The ratio of their dimensions is  R .

So  R³  is        729 / 2744 .

Take the cube root of that and you'll have  R .

Then square R and you'll have the ratio of their surface areas.
