Aworkbox has the following interior dimensions: length - 5" width - 31/2 " height - 4" what is the interior volume of the workbox

The volume V of the workbox can be calculated by the formula: 

V=a*b*c where a is the length, b is the width and c is the height.

In our case a=5'', b=31/2'' and c=4''. 

When we input the numbers in the formula we get: 

V=5*(31/2)*4=310 in³

So the interior volume V of the workbox is V=310 in³.
