Question 1137593
<br>
The new prism with all dimensions doubled is similar to the original, with a scale factor 2:1.<br>
In similar figures with scale factor a:b, the ratio of corresponding area measurements is a^2:b^2, and the ratio of corresponding volume measurements is a^3:b^3.<br>
So in this problem, with a scale factor of 2:1, the ratio of areas is 4:1; that means the surface area of the new prism is 4*450 = 1800 m^2.
