Qhov ntim ntawm a lub tog raj kheej yog lub square ntawm nws lub voj voog lub sij hawm pi lub sij hawm qhov siab. Yog li lub ntim ntawm koj khoob lub tog raj kheej yog (22)(pi)(4) -(1.52)(pi)(4). Qhov no yog hais txog 22 cubic feet. Yog koj lub tog raj kheej yog ua los ntawm pob zeb, uas feem ntau yog hais txog 144lbs ib cubic feet, ces nws yuav hnyav Luas = 22 x 144 = 3168 lbs.
