Cov kev tsim kho tshwj xeeb yuav tsum tau txiav txim siab ntawm qhov chaw muaj kev tsim kho ntawm txoj haujlwm, thiab muaj feem xyuam rau qhov siab ntawm tus ncej, qhov sib nrug ntawm tus ncej ntsug, tus ntoo khaub lig-bar, thiab cov kauj ruam deb.
Piv txwv li: qhov kev sib tw ntawm cov kab rov tav thiab ntsug ntawm tus ncej yog 1m, lub sijhawm sib nrug yog 1.5min meTers (piv txwv li ntawm 2m), ces tag nrho cov nqi ntawm tus ncej yog:
1. Ntev ntawm ib-txheej thav duab: (2 + 1) * 5 + (5 + 1) * 2 = 27 hli
2. Nrog cov kauj ruam deb ntawm 1.8m thiab ib qho siab ntawm 2.8m, muaj peb txheej ntawm txee, yog li tag nrho cov txheej ntawm peb txheej yog 27 * 3 = 81m
3. Tus ncej yog: 6 * 3 = 18, qhov siab yog 2.8 * 18 = 50.4m
4. Tag nrho cov nyiaj ntawm tag nrho cov thav duab ntawm 10 square metres (tsis suav nrog pob txha caj dab, kab pheeb ces caj npab, thiab lwm yam) 81 = 131.4M
