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

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.

V=1/3*20.4*43560*69

and according to google 1ft2=0.0283168466 m3

so I get 578,749.7m3
