A gift box shown below is packed with small cubic 1/2 inch blocks. The blocks are packed tightly with no spaces between them.
svetlana [45]

Step-by-step explanation:

the box is

9 in × 3.5 in × 4.5 in = 141.75 in³

each block is

0.5 in × 0.5 in × 0.5 in = 0.125 in³ (1/8 in³)

so, we can fit

141.75 / 0.125 = 1134

blocks into the box.

and they fit neatly, as the dimensions of the box and the cubes allow a tight packing without any empty left over space in the box.

An externally imposed project completion time sets the project duration at 75 days. The critical path of the project is establis
Katen [24]

Answer:

3 days

Step-by-step explanation:

This can be seen under Schedule management (Initiating)

Project float is simply the difference between the completion period externally imposed and the estimated time duration of the project (usually this is equal to the critical path length). The difference in this case is 0 because

Externally imposed project date = 75 days

Estimated duration of project = 75 days

Hence, a difference in these will be 0

However, a standard deviation of 3 days was giving (This implies that there is a +/- 3 days in the critical path from the estimated project duration) .

Hence the maximum float in this case will be 0 + 3 = 3 days
