Someone help find surface area of a right rectangular prism

Mathematics
1 answer:
Bond [772]3 years ago
3 0

Answer:

51 square units

Step-by-step explanation:

First you act like each side is it’s separate rectangle.

Then you would multiply 2 and 4 to get 8, the area of one of the sides. Then you would multiply 2 and 2.5 to get 5, the area of another side. Then 2.5 times 5 to get 12.5, the last side. Now sense every side has a side the same size of itself you would take each answer and multiply it by to to get 8x2=16, 5x2=10, and 12.5x2= 25. You would add together 16, 10, and 25 to get 51 square units, the surface area.

What is 6 divided by 7/9
Hunter-Best [27]

Answer:

54/7

Step-by-step explanation:

  1. Use the KCF method - Keep, Change, Flip
  2. 6 divided by 7/9 is just 6/1 divided by 7/9
  3. You can keep 6/1 as the way it is
  4. Next, you change the sign from division to multiplication
  5. Lastly, you flip 7/9 to 9/7
  6. It will now change from 6 divided by 7/9 to 6/1 x 9/7
  7. You now multiple 9 x 6 which is 54 and divide by 7
  8. You cannot simplify further so the answer is 54/7

A package is 15.5 inches long, 8.25 inches wide, and 5.5 inches high. What is the volume of the box? Enter your answer, rounded
Dmitriy789 [7]

Answer: 703.3125 in cubed

Step-by-step explanation:

The formula to find the volume of something is to…

1. Find the area of the base! Remember, area is length x width. In this case we would have 15.5 x 8.25 = 127.875

2. Multiply the base area we just found by the height! In this case, we take 127.875 x 5.5 and this gives us 703.3125 as our final answer!
