Answer:
Lateral surface area = 4 (1/2 × 705 × 588.30) = 829503 ft²
Step-by-step explanation:
The pyramid is a square base pyramid. The height = 471 ft. The sides of the square base pyramid = 705 ft.
To calculate the lateral area of the square base pyramid we have to know the slant height. The slant height can be known by using Pythagoras theorem to solve for it.
c² = a² + b²(Pythagoras theorem)
base = b = 705/2 = 352.50 ft
c² = 352.50² + 471²
c² = 124256.25 + 221841
c² = 346097.25
square root both sides
c = √346097.25
c = 588.300305966
c ≈ 588.30 ft
slant height = 588.30 ft
Lateral surface area = sum of area of the 4 triangular faces
lateral surface area = 4 (1/2 × base × height)
Lateral surface area = 4 (1/2 ×705 × 588.30) = 829503 ft²
Answer:
The 30-minute meeting of eight mechanics being paid $16 an hour, costed the garage $64!
Step-by-step explanation:
First, identify what you know:
1) A single mechanic is paid $16 an hour.
2) Eight mechanics, being paid $16 an hour, met.
3) The meeting lasted 30 minutes, or half an hour.
If a mechanic makes $16 dollars in one hour (60 min), how much would they make in half an hour? Since they worked for half an hour, they'd make half an hour wage!
$16/2 = $8
So, now if each of the eight mechanics were paid $8 for the half hour meeting, how much would it cost the garage?
$8 x 8 = $64
The garage would have had to pay $64 in total to the mechanics for their 30 minute meeting.
