How might building canals have improved the empire

Explanation:

Canals allowed a greater volume of goods to be moved more precisely, and for much less, opening up new markets in terms of location and affordability. Seaports could now be connected to inland trade. Canals allowed for the greater exploitation of coal reserves as the coal could be moved further, and sold cheaper, allowing a new market to form. Industries could now relocate to coalfields or move to towns, and the materials and products could be moved either way. Of over 150 canal acts from 1760 to 1800, 90 were for coal purposes.
