The volume of a cube is just the side length cubed...
V=s^3 in this case:
V=39^3=59319 ft^3
and in cubic yards it is:
59319 ft^3*(yd^3/27 ft^3)=2197 yd^3
1745 can be divided by any number, however, it will most likely have decimals.
The event that either M1 or M2 fails has probability

by the addition rule. Failure events are independent, so

so that

Denote this probability by
. Then
follows a geometric distribution with this parameter
and has density

The expectation is
.
