162 is not a perfect square therefore you have to find the largest perfect square that can go into 162 which would be 81.
Answer:
Edge = 12
Total Surface Area = 72
Step-by-step explanation:
Volume of the cube = 1728
Length of the edge = ![\sqrt[3]{1728} = 12](https://tex.z-dn.net/?f=%20%5Csqrt%5B3%5D%7B1728%7D%20%20%3D%2012)
We know that
TSA (Total Surface Area) = 
where a = length of edge of cube
So,
TSA of cube = 
Straight lines will always add up to 180 degrees, so the angle that is missing here is supplementary to the other angle(adds up with the other angle to get 180) so we take 79 away from 180 and get 101 degrees
