It is: 2m times 2m is equivalent to 4m^2
6m + 7 - 2m + 1 = 4m + 8 If you meant: (6m + 7) - (2m + 1) = 4m + 6
The rate for one man to finish a 2mx2mx2m whole is... 1 man = 8m3 per day At the same rate three men can each do a 2mx2mx2m whole. This is how much they altogether can do in one day. 3 men = 24m3 per day The whole they have to dig is this size. 4mx4mx4m which is 64m3 Since three men can do 24m3 per day it will take them 2 days and 16 hours to dig a 64m3 hole.

The triangle with side lengths of 2m, 4m, and 7m does not form a valid triangle. In a triangle, the sum of the lengths of any two sides must be greater than the length of the third side according to the Triangle Inequality Theorem. In this case, 2m + 4m is less than 7m, violating the theorem. Therefore, a triangle with these side lengths cannot exist in Euclidean geometry.
