Which formula gives the volume of a rectangular solid?

LWH
2LW + 2WH + 2LH
4(3.14)(r^2)
(3.14)(r^2)(h)

The correct answer is: LWH

The formula for calculating the volume of a rectangular solid is derived from the three dimensions that define its size: length, width, and height. The formula essentially multiplies these three measurements together: length (L), width (W), and height (H). Thus, the correct formula for the volume of a rectangular solid is $ L \times W \times H $, which is represented by the formula given. This direct multiplication gives you the total amount of three-dimensional space that the solid occupies. To provide context regarding the other options: the formula that involves $ 2LW + 2WH + 2LH $ is actually the formula for the surface area of the rectangular solid, not the volume. The formulas involving $ 3.14 $ and $ r $ are associated with calculations for circles or cylinders, specifically for their area and volume, respectively, which do not apply to rectangular solids.
