Given:
Dimensions of a rectangular prism are 6 meters by 3 meters by 12 meters.
To find:
The surface area of the prism.
Solution:
The surface area of a rectangular prism is:
![A=2(lb+bh+hl)](https://tex.z-dn.net/?f=A%3D2%28lb%2Bbh%2Bhl%29)
Where, l is length, b is breadth and h is height.
Putting
, we get
![A=2(6\times 3+3\times 12+12\times 6)](https://tex.z-dn.net/?f=A%3D2%286%5Ctimes%203%2B3%5Ctimes%2012%2B12%5Ctimes%206%29)
![A=2(18+36+72)](https://tex.z-dn.net/?f=A%3D2%2818%2B36%2B72%29)
![A=2(126)](https://tex.z-dn.net/?f=A%3D2%28126%29)
![A=252](https://tex.z-dn.net/?f=A%3D252)
Therefore, the surface area of the prism is 252 square meters.
Answer:
kilgore, 140 miles
Step-by-step explanation:
16,900,000 in scientific notation is 16.9 times 10^7.
When you move the decimal point to the 1, it goes 7 spaces to the left, so the exponent will be a positive 7.
Answer:
105
For the 4 triangular faces, find the area with 1/2 × base × height = 1/2 × 5 × 8 = 20
4 triangles -> 20 × 4 = 80
The area of the square base is 25
80 + 25 - 105 ![cm^{2}](https://tex.z-dn.net/?f=cm%5E%7B2%7D)
