Answer:
42.875 cm^3
Step-by-step explanation:
Since cubes have the same length, width, and heigh measurements all around we can infer that every side is equal to 3.5 cm.
V = base × height × width
V = 3.5 cm × 3.5 cm × 3.5 cm
V = 42.875 cm^3
So for the Area you would do Length x width, for a square the length and width are equal so if you take the square root of 1/16 you get 1/4
