Question

If one side of cube is 27 cm then find the length of longest diagonal​

Answer 1

Answer:

I'm going to assume 27 is the edge length and not surface area

Step-by-step explanation:

since we know it is cube, all ides are automatically 27. First we need to find the diagonal of a square.

$\sqrt{27^{2}+27^{2} }$=$\sqrt{1458}$

now to find the longest diagonal (which is going in length, height, and depth from on corner to the oppisite corner) we need to do $1458+27^{2}$ and square root that.

$\sqrt{2187}$ this is your answer
