Oh, really sorry. I didn't notice that. So, it should be 400,000L.

Actually, I wrote the unit as litres because you're measuring the volume of water.

irspow is right! A metre³ of any substance is 1,000 litres!

2006-01-11 08:58:50

I might be nitpicking but VR Hawks posted a solution of 400L when the answer was 400m³.  That would be 400,000L of water.

Nice post, VR Hawks smile Its interesting to note that you are from Hongkong.

Actually, I noticed that MathIsFun was and is our "emperor" and captain, a captain with capable knowledge to solve our problems. smile

You have realized that a bit too late. I knew that he had a lot of sense and was a friendly person the day I registered in the forum. MathsIsFun is our Commander. smilesmilesmile

You've got sense, MathIsFun!

Not curious...the area formula for a cone is 1/3 the area of a cylinder.  Actually a cone is just a tapered cylinder anyway.

Curious fact: the water would fill a cone of the same dimensions.

To find out the cylindrical container's total volume, refer to the calculations below.

Base Area x Height = Volume

100 x 12 = 1200 L

And to find out 1/3 of it, times the total volume by 1/3 or devide the total volume by 3.

1200/3 = 400 L

1200 x 1/3 = 400 L

The volume of the cylinder is the base time the height and you are given that information.

V = 100× 12 = 1200

If the cylinder is 1/3 full then the water volume is 1/3 the volume of the cylinder;

1200/3 = 400 m^3

a cylindrical container has a base area 100 m2 and is 12 m high. if the container is one-third filled with water, what is the volume of the water in the container?
