The volume V of a certain solid is twice the product of pi and the cube of its length L.

V = 2(pi * L^2)

or
V = 2pi * 2L^2

Translate the verbal description into a mathematical formula.

The volume Upper V of a certain solid is one dash fourth the product of pi and the cube of its width w.

The expression that represents the volume V of the solid is: V = 2πL³

The volume V of the solid is expressed as:

V = 2πL³

This equation represents that the volume (V) is equal to twice (2) the product of pi (π) and the cube (³) of the length (L) of the solid.
