The total volume of barley Joyce Johnson has in the two open containers is 5 lb 4 oz.
This is the unit of a three-dimensional measure of space that comprises a length, a width and a height. It is measured in units of cubic centimeters in metric, cubic inches or cubic feet.
Total barley in the containers = container 1 + container 2
= 3lb 15oz + 1lb and 5oz
= 4 lb 20 oz
16 oz = 1 lb
20 oz = 1 lb 4 oz
So,
4 lb 20 oz
= 5 lb 4 oz
Therefore, the total volume of barley Joyce Johnson has in the two open containers is 5 lb 4 oz
