How to calculate area when you are given volume of 182m3 and height of 2.8m

Elza [17]

Hey there!

We simply have to do 182/2.8, and you will get the area (65m^2).

We know that the formula for area is length x width, and the formula for volume is length x width x height. In the volume formula, we can see it can also be area x height to get volume. So, we know that area x height = volume, right? And in this equation, we are given volume and height. If V = ha, with V = volume; h = height; a = area, we can divide "h" on both sides, and we get V/h = a, or volume divided by height is area. To solve for the above equation, we can plug the numbers in the formula: 182/2.8 = a, or 65 = a.

Hope this helps! Have an amazing day, and remember, you've got this!

My friend helped me with this and since I saw no answer here I wanted to help YOU!!!!

So the first one was easy because it already said it in the number line.

The second one you simply multiply 2x 2 1/2

The third one you multiply 4x 2 1/2.
