Question

It cost $136 to fill a 8 ft by 5 ft by 2 foot sand box with sand. How much will it cost to fill a 12 ft by 6 ft by 1 ft sand box?

Answer 1

Answer: $122.40

Explanation:

We need to find the cost per square foot so to do that we need to find the volume of the sand box.

To do so we multiply 8ft x 5ft x2ft.

8x5x2=80

Now we find price per sq foot by setting the equation up like this 136/80.

This comes out to $1.7 per foot.

Now we need to find the volume of the second box. to do so multiply 12x6x1 to get 72.

Now multiply the volume of the second box by 1.7 to get 122.4.
