problem, the symbols M, L, and T represent the dimensions mass, length, and time, respectively. Consider the physical quantities V, ρ, and t with dimensions [V] = L3, [ρ] = ML-3, and [t] = T. (Here, the square bracket means “the dimensions of” so, for example, [V] represents the dimensions of the quantity V.)What are the dimensions of ∫ρdV? What are the dimensions of dV/dt?   What are the dimensions of ρ(dV/dt)?
