Question from Darrell, a student:

A trough that measures 4 feet long, 22 inches wide, and 18 inches high will be mounted
on a support stand. If the trough weighs 50 pounds when empty, approximately how many
pounds must the stand be able to hold when the trough is full of water?

Darrell,

Convert all the dimensions to feet. Find the volume in cubic feet. How much does a cubic foot of water weigh?
