**Henry**, Tuesday, May 24, 2011 at 11:27amThe following areas are equal:

1. Front and Back.

2. Left and right.

3. Top and Bottom.

Therefore, we calculate 3 areas and

multiply each by 2 to get the 6 areas:

As=2(3*h) + 2(10*h) + 2(10*3)=1901n^2.

6h + 20h + 60 = 190,

26h = 190 - 60 = 130,

h = 5in.
