Question

(A) how many cubic meters of sand can the sandbox hold? (B) the manufacture suggested the sandbox should be filled to 89% capacity. How many cubic meters of sand is this?

Answer 1

To solve this problem, we must find the volume of the sandbox.

`V=l\cdot w\cdot d`

Where:

`\begin{gathered} l=30m \\ w=26m \\ d=4m \end{gathered}`

Now, we replace and solve:

`\begin{gathered} V=30m\cdot26m\cdot4m \\ V=3120m^3 \end{gathered}`

The A answer is 3120 cubic meters

Now, for question "b" we must find how many cubic meters are 89% of its capacity, that is 89% of the capacity of the 3120 cubic meters.

For this, we multiply the total capacity of the sandbox by 0.89.

`3120\cdot0.89=2776.8`

The A answer is 2776.8 cubic meters
