Find the volume of the pyramid, given its slant height. Round them to the nearest tenth please. Can you help me? I tried but I did not understand and thank you

  4.  1.3 cm³

  5.  621.2 mm³

  6.  116.5 m³

Step-by-step explanation:

The height to the peak of the pyramid is one side of the right triangle that has its hypotenuse equal to the slant height, and one leg equal to half the base side length. The Pythagorean theorem is used to find the height from the slant height (s) and the base length (b):

  h = √(s² -(b/2)²)

The volume is found from the formula ...

  V = (1/3)b²h

where b is the base length and h is the height found using the previous formula.

The tedious arithmetic is nicely done using a spreadsheet. Results are attached.

4/6 = 2/3

so it should take 3/3 hours per man. so 9 hours is the answer 3*3 =9
