1hr/3600sec=15hr/x
(3600sec)(15hr)=(1hr)x
x=54000seconds
15 hours is 54000 seconds
Answer:
816 cm²
Step-by-step explanation:
Surface area of the composite figure = (surface area of the larger rectangular prism + surface area of the smaller rectangular prism) - area of the side of the smaller rectangular prism that is joined to the bigger prism.
✔️Surface area of the larger rectangular prism:
Area = L*W*H = 20*5*6 = 600 cm²
✔️surface area of the smaller rectangular prism:
Area = L*W*H = 12*4*6 = 288 cm²
✔️area of the side of the smaller rectangular prism that is joined to the bigger prism.
Area = L*W = 12*6 = 72 cm²
Surface area of the composite = (600 + 288) - 72 = 888 - 72 = 816 cm².
This is probably in the context of a discussion of significant figures and accuracy.
When we record a measurement of 4.15 cm with two significant figures, that means we believe the exact value is in the range from 4.145 cm to 41.155 cm
Similarly 7.34 really means between 7.335 and 7.345 cm.
The minimum area rectangle is
![4.145 \times 7.335 = 30.403575 \approx 30.40](https://tex.z-dn.net/?f=4.145%20%5Ctimes%207.335%20%3D%2030.403575%20%5Capprox%2030.40)
The maximum area rectangle is
![4.155 \times 7.345 =30.518475 \approx 30.52](https://tex.z-dn.net/?f=4.155%20%5Ctimes%207.345%20%3D30.518475%20%5Capprox%2030.52)
