In the shed problem, machinery occupies $300\,\mathrm{m}^3$ and 20 workers occupy $0.08\,\mathrm{m}^3$ each on average. If the total empty-shed volume is $1128.75\,\mathrm{m}^3$, how much air is in the shed?
A$828.75\,\mathrm{m}^3$
B$827.15\,\mathrm{m}^3$
C$826.55\,\mathrm{m}^3$
D$830.35\,\mathrm{m}^3$
Answer & Solution
Correct answer: B. $827.15\,\mathrm{m}^3$
Total occupied space $=300+(20\times0.08)=300+1.6=301.6\,\mathrm{m}^3$. Hence air in the shed $=1128.75-301.6=827.15\,\mathrm{m}^3$.
