How do you calculate the volume of a rectangular solid?

Length x Width x Height
Length + Width + Height
2(Length + Width + Height)
Length x Width - Height

The correct answer is: Length x Width x Height

To calculate the volume of a rectangular solid, the formula used is Length x Width x Height. This formula takes into account all three dimensions of the rectangular solid, providing the total three-dimensional space it occupies. It is derived from the geometric understanding that volume measurement is concerned with how much space an object occupies. In the case of a rectangular solid, you multiply the length of the object by its width to find the area of the base. Then, multiplying that area by the height gives the total volume. This multiplication reflects the cubic nature of the measurement, since volume is expressed in cubic units, such as cubic centimeters or cubic meters. The other options reflect different mathematical operations which do not correspond to calculating volume. The addition in one of the alternatives simply sums the dimensions but does not measure space; the other constructs either lead to a perimeter calculation or an incorrect mathematical operation by subtracting one dimension from the product of the other two.
