Answer:
273.62 cm^2
Step-by-step explanation:
so surface area of a rectangular prism is 7*6 7*2 and 6*2 (this can be used with different numbers, i dont know how to explain it well) this would come out to 68
the trangular prism doesnt have a direct formula, but there are calculators on the internet you can look up, but it would come out to 205.62,
add the numbers together and you would get 273.62cm^2
Octagon, stop sign.
Eight isoscles triangles. It looks like we're told the side is 9.9 and the height to the side (also called the apothem) is 12.
So each isosceles triangle has area (1/2)(9.9)(12) and we have eight of them,
area = 8(1/2)(9.9)(12) = 475.2
Answer: 475.2
Usually we wouldn't be told 9.9 -- this is the baby version. We know each of those isoscles triangles has unique angle 360/8=45 degrees, so the apothem and half the side of the octagon are a right triangle with acute angle 22.5 degrees.
The area of the right triangle with long leg 12, short leg x,
tan 22.5 = x/12 or
x = 12 tan 22.5
Twice that is what we're told is 9.9; let's check:
2x = 24 tan 22.5 = 9.941125496954282
The area of the little right triangle is
(1/2) 12 × 12 tan 22.5
and there are 16 of these
16 (1/2) 12 × 12 tan 22.5 ≈ 477.174
The answer should be $650 because, $100 a day for five days is $500. Then the overtimes for three days would equal up to $150 in overtime. $500 + $150 = $650
