  1. Aug 29, 2009 #1
    1. The problem statement, all variables and given/known data

    The base of a pyramid covers an area of 20.4 acres (1 acre = 43, 560 ft^2) and has a
    height of 69 ft.

    Find the volume of this pyramid in cubic meters. Answer in units of m3.

    2. Relevant equations

    V of Pyramid= (1/3)bh

    where 'b' is 43,560 ft^2

    3. The attempt at a solution

    My attempt at the solution got me 28370.082 cubic meters after converting.

    Don't you mean b= 43,561*20.4 ft2?

    Also how many m= 1 ft?

    Yes thats what i meant. I just redid my solution. Several figures off lol. But please, attempt the problem so i can check my answer

    might i add that the question wants the answer in sigfigs

    also about the conversions. let's just find the answer in cubic feet first. the conversion can be done afterwards

    I was asking because I didn't know.


    and according to google 1ft2=0.0283168466 m3

    so I get 578,749.7m3
