Express the length of a cube by the function of the cubes diagonal length d then express the surface area and volume of the cube as a function of the diagonal length

d

The length of the cube is equal to the square root of 3 times the diagonal length d.

The surface area of the cube is equal to 6d^2.

The volume of the cube is equal to d^3.

AAAaannndd the bot gets it wrong yet again!

d^2 = 3s^2, so
s = d/√3
A = 6s^2 = 2d^2
V = s^3 = d^3/√27
