In this case l = 4 ft., w = 1ft, h=21 inches. Convert inches to feet (divide by 12). So h = 21/12 = 1.75 ft. Volume - 4*1*1.75= 7 cubic feet. There are appox. 7.48 gallons for each cubic foot. So multiply: 7*7.48=52.36 gallons. I provide online tutoring (\$30/hr) and personal problem solving (\$3.50-\$5.50 per problem. Contact me (check the profile "website" which is my email address.
