Surface area of cube = 6 * l^2 where l is the length of the edge of the cube
6l^2=48
/6
l^2=8
sqrt%28l%5E2%29=sqrt%288%29
l=2sqrt%282%29

There are 6 faces on a cube
Each face has an area of +s%5E2+
where s is a side of the cube
+A+=+6s%5E2+
+48+=+6s%5E2+
+s%5E2+=+8+
+s+=+2%2Asqrt%282%29+
The length width and height of the cube is +2%2Asqrt%282%29+
