Question

How much money will the sand from the sandbox cost?

Answer 1

Let us find the volume of the sandbox. The sandbox is a rectangular prism. Therefore, the volume of a rectangular prism can be found below

`\begin{gathered} \text{volume}=\text{lwh} \\ \text{where} \\ l=\text{length}=\text{ 4 ft} \\ w=\text{width}=5\text{ ft} \\ h=\text{height}=2\text{ ft} \\ \text{volume}=4*5*2=40ft^3 \end{gathered}`

Therefore,

`\begin{gathered} 0.5ft^3\text{ = \$2.84} \\ 40ft^3=? \\ \text{cross multiply} \\ \text{cost to fill the sand box=}(40*2.84)/(0.5)=(113.6)/(0.5)\text{ = \$}227.2 \end{gathered}`

cost to fill sandbox = $227.2
