Question

the volume of a rectangular solid is 810m^3. Find its dimension is they are in the ratio of 2:3:5

Answer 1

So what's a ratio say? So if you have 7:10 as a ratio of sheep to horses, that means for every 7 sheep you have, you must have 10 horses.

So 21 sheep means you also have 30 horses.
So an equation might look like this:

7x=10x

where x represents how many multiples of 7 sheep you have.

Answer 2

Volume of a rectangular solid is length * width * height.

Answer 3

And for the ratio of the dimensions to be 2:3:5, you would need to multiply the side lengths by a constant so that when you multiply the together, you get your volume given.

Answer 4

For example, 4*6*10=240, so that is not the answer, but the ratio is right.
