To determine

The basal metabolism(BM) of an organism for $1$ day, if $BMR\left(t\right)=0.4+0.2\cos \left(\raisebox{1ex}{$\pi t$}\!\left/ \!\raisebox{-1ex}{$12$}\right.\right)$ kcal per hour, where the basal metabolism(BM) of an organism over a certain time period may be described as the total amount of heat in kilocalories(kcal) that the organism is at rest and not subject to stress.
