What is the formula to compute load weight from volume?

• A. Width x Height x Length
• B. Area x Density
• C. Volume in cubic feet x Weight per cubic foot
• D. Weight per cubic foot x Volume in cubic inches

Answer: (C)

Weight is found by multiplying volume by weight density. Volume tells how much space something occupies, and weight density (weight per unit volume) tells how heavy each unit of that space is. Multiply the two to get the total load weight. Using volume in cubic feet and weight per cubic foot keeps the units aligned, giving pounds as the result (ft^3 × lb/ft^3 = lb). The other options don’t fit because they mix dimensions in ways that don’t yield a total weight: width × height × length gives volume but not weight; area × density uses area (two dimensions) times a per-volume measure, which isn’t consistent for total weight; and multiplying weight per cubic foot by volume in cubic inches requires converting units, which isn’t as straightforward.
