width: 13 cm

height: 10.5 cm

If all the dimensions of the prism are doubled, what will be its new surface area?

1,298 cm2

4,192 cm2

2,596 cm2

4,368 cm2

**Reiny**, Friday, January 18, 2013 at 12:07pmif each dimension is doubled, the surface area will be quadrupled, that is, multiplied by 4

so find the original area, multiply the answer by 4 and see if you find a match

(I see one, and it is not in the first two )
