Direct proportion
Because of the conical shape of the container, the value of a bin of mineral sand is directly proportional to the square root of the height of mineral sand in the container.
If the value of the sand in the container is $5m when the height is 9 metres, what will be the value when the height is 16 metres?

Look through the options below and select the one you think is the best response. You will gain most benefit if you work the problem with pen and paper as you go, i.e. decide what you think is the correct option and write down what you think the result will be before you click. If the next step doesn't display, click another option.
How do you connect the quantities?
