A tank of a MODU, with a volume of 2,000 cubic feet, is pressed up with sea water weighing 64 pounds per cubic foot. What is the weight, in kips, of the liquid?
• Basic weight calculation: Total weight = volume × weight density • Unit conversions between pounds and kips (1 kip = 1,000 pounds) • Careful multiplication with powers of 10 to avoid simple arithmetic mistakes
• First find the total weight of the seawater in pounds using the given volume and weight per cubic foot. What single multiplication do you need? • Once you have pounds, how do you change that number into kips? What do you divide by? • After converting to kips, which of the choices is closest to your result, making sure you did not round too early?
• Confirm you multiplied 2,000 cubic feet by 64 pounds per cubic foot before doing any conversion. • Verify you used 1 kip = 1,000 pounds for your conversion. • Double-check your arithmetic, especially the number of zeros, before matching to the multiple-choice options.
