Answer:. 9/16
Step-by-step explanation:
The dilation scale is applied to the dimensions of the edges of the faces.
The original was, for example, 1×1, so the area of each face is 1 square unit.
The dilated edge is 3/4.
3/4 × 3/4 is 9/16
The surface area of the entire cube is reduced by that factor.
