Answer:

The sides are 3 and 7 cm long.

Step-by-step explanation:

Let the lengths be x and x+4 cm, then

(x + 4)^3 - x^3 = 316

x^3  + 12x^2 + 48x + 64 - x^3 = 316

12x^2 + 48x + 64 - 316 = 0

12x^2 + 48x - 252 = 0

12(x^2 + 4x - 21) = 0

12(x + 7)(x - 3) = 0

x = -7, 3

So one cube has side of length  3 cm.

The other has side 3+4 = 7 cm.

Step-by-step explanation:

Option : Use distance formula to prove that the lengths of the diagonals are equal" is correct.

Because " By using the coordinate geometry to prove that the diagonals of the rectangle are congruent, first we have to find the lengths of the top and bottom of the rectangle and then solve it for the lengths of the diagonals by using the distance formula".
