Choose 1 answer
15 + 15 + 15 + 15 +6
2.6+2.10+2-15
3.5.2
15+ 6+6+ 10 + 10

Answer 1

To find the surface area of a right rectangular prism, find the area of each face and add them together.

Step-by-step explanation:

The surface area of a right rectangular prism can be found by finding the area of each face and adding them together. In this case, the prism has 6 faces. The area of the top and bottom faces is length times width, which is 5 times 5 = 25. The area of the front and back faces is length times height, which is 5 times 2 = 10. The area of the left and right faces is width times height, which is 5 times 2 = 10. Therefore, the expression that represents the surface area of the prism is 25 + 25 + 10 + 10 + 10 + 10 = 80.

Answer 2

I believe the answer would be B: 2*6 + 2*10 +2*15

Step-by-step explanation: First you could do 3*5 which would get you 15 and since there are two sides for this one it would be 2*15.

Then You could do 2*3 which gives you 6 and multiply that by 2.

Finally you would do 2*5 and you get 10 then multiply that by 2.

It would equal 62 which is equal to the expression of Answer B.
