The side length, s, of a cube is 3x 2y. If V = s3, what is the volume of the cube? 3x3 18x2y 36xy2 8y3 27x3 54x2y 18xy2 2y3 27x3 18x2y 12xy2 2y3 27x3 54x2y 36xy2 8y3.

You have 2 sides that are 2 cms and you have 6 sides that are 1/2 cm and you have 4 sides that are 1 cm. the smallest sides are 1/2 the medium sized sides are 1 and the smallest are 1/2. so to find the perimeter you have to add them all up together so your answer will be 11 cm's
