Answer :
The customer bought more sand than is needed to fill the sandbox.
Solution:
A toy company makes rectangular sandboxes that measure 6 feet by 5 feet by 1.2 feet
Find the volume of box
[tex]Volume = length \times width \times height\\\\Volume = 6 \times 5 \times 1.2\\\\Volume = 36\ feet^3[/tex]
A customer buys a sandbox of 40 cubic feet of sand
We know that,
40 cubic feet > 36 cubic feet
Thus,
volume of sand > volume of rectangular sandboxes
Therefore, the customer bought more sand than is needed to fill the sandbox.
