Express the edge length of a cube as a function of the cube's diagonal length d. Then express the surface area & volume of t
he cube as a function of the diagonal length.
2 answers:
D = sqrt(3s^2) where s is the length of the side. Solving for s,
<span>3s^2 = d^2 iff </span>
<span>s^2 = d^2 / 3 iff </span>
<span>s = sqrt(d^2 / 3) </span>
<span>= d / sqrt(3) or d sqrt(3) / 3 </span>
<span>Surface area of the cube = 6 s^2. Thus, </span>
<span>A = 6 (d / sqrt(3))^2 </span>
<span>= 6d^2 / 3 </span>
<span>= 2d^2 </span>
<span>Volume = s^3. Thus, </span>
<span>V = (d / sqrt(3))^3 </span>
<span>= d^3 / 3sqrt(3) </span>
<span>= d^3 sqrt(3) / 9</span>
D = sqrt(3s^2) ,
<span>3s^2 = d^2 </span>
<span>s^2 = d^2 / 3 </span>
<span>s = sqrt(d^2 / 3) </span>
<span>= d / sqrt(3) </span>
now we will find surface area
therefore
<span>Surface area of the cube = 6 s^2.</span>
<span>Area = 6 (d / sqrt(3))^2 </span>
<span>= 6d^2 / 3 </span>
<span>= 2d^2 </span>
now we shall find volume
<span>V = s^3.</span>
<span>V = (d / sqrt(3))^3 </span>
<span>= d^3 / 3sqrt(3) </span>
<span>= d^3 sqrt(3) /9
