Answer:
20.833 feet
Step-by-step explanation:
The light reflects off the mirror at the same angle that it hits it at. So the triangle formed by the beam and mirror is similar to the triangle formed by Kevin and the mirror.
Therefore, we can write and solve a proportion.
h / 10 = 6.25 / 3
h = 20.833
The beam is 20.833 feet tall.
If the face is a square, then (l*l)
If the face is a triangle, then (b*h)(1/2)
If the face is a rectangle, then (l*w)
If the face is a circle, then (r²)(3.14)
You can then add all these faces up to get the total surface area of the prism.
