Find the surface area of each rectangular prism or cylinder to the nearest tenth of a degree.

7. Bases are isoceles triangles with legs that measure 5 centimeters. The height is 7 cm.

I Don't know how to set it up. What formula do i use and how? Thanks

<Find the surface area of each rectangular prism or cylinder to the nearest tenth of a degree>

Areas are not measured in degrees. Would you mind restating the question?

oops! tenth of a square unit.

To find the surface area of a rectangular prism or cylinder, we need to calculate the sum of the areas of all its faces.

In this case, we have a rectangular prism where the bases are isosceles triangles with legs measuring 5 centimeters, and the height is 7 centimeters.

To calculate the surface area, we need to find the area of each face and sum them up.

1. Start with the area of the two bases (isosceles triangles):
- Since the legs of the triangle measure 5 centimeters, the base of each triangle is also 5 centimeters.
- To find the height of each triangle, we can use the Pythagorean theorem: h^2 = 5^2 - (5/2)^2.
- Calculate h = √(25 - 6.25) ≈ 4.53 centimeters.
- Therefore, the area of each base triangle is (1/2) * base * height = (1/2) * 5 * 4.53 ≈ 11.33 square centimeters.

2. Move on to the other four faces:
- These are all rectangular in shape, with dimensions consistent with the prism's overall measurements.
- The dimensions are: length = 5 centimeters, width = 5 centimeters, and height = 7 centimeters.
- Calculate the area of each rectangular face as length * width = 5 * 7 = 35 square centimeters.

3. Add up all the face areas:
- The sum is: 2 * (11.33) + 4 * (35) = 22.66 + 140 ≈ 162.66 square centimeters.

Therefore, the surface area of the given rectangular prism is approximately 162.7 square centimeters (rounded to the nearest tenth).
