<p>I was wondering if someone could help me with this math problem in my KAPLAN SAT book.</p>

<p>A wooden cube with a volume 64 is sliced in half horizontally. The two halves are then glued together to form a rectangular solid which is not a cube. What is the surface area of this new solid.</p>

<p>A) 48
B) 56
C) 96
D) 112
E) 128</p>

<p>I'm bad at math <:</p>

<p>The volume of a cube is x<em>x</em>x (i.e. x cubed), where x is the length=depth=height of the cube. So x is 4 (4<em>4</em>4 = 64).</p>

<p>The surface area of a rectangular solid is the sum of the areas of the sides. There are 6 sides. Two of them are 8<em>2, two are 8</em>4, and 2 are 4*2 – so 112.</p>
