Answer:
Step-by-step explanation:
<u>Surface area:</u>
- S = 2(lw + lh + wh) + 2πrh
- S = 2(9*4 + 9*5 + 4*5) + 2*3.14*2*3 = 239.7 cm² (rounded)
<u>Volume:</u>
- V = lwh + πr²h
- V = 9*4*5 + 3.14*2²*3 = 217.7 cm³ (rounded)
Answer:
26
Step-by-step explanation:
One person can pack 45 cartoons per hour
Therefore the number of people needed to pack 1200 cartons can be calculated as follows
