Don't you mean b= 43,561*20.4 ft²?

Also how many m= 1 ft?

Yes that's 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.

V=1/3*20.4*43560*69

and according to google 1ft²=0.0283168466 m³

so I get 578,749.7m³

thanks that's what i got. this problem was extremely simple i was just exhausted and tried skipping steps foolishly.

guess its time to close this thread
