Answer: A. 184.8ft2
Step-by-step explanation:
The pyramid is made up of four sides that are rectangular, each side has a height of 12.4ft and base length of 6ft.
The base area is a square of 6ft by 6ft.
For the sides, area of a triangle is 1/2 x base x height
= 1/2 x 6 x 12.4 = 37.2m2
For the four triangles = 4 x 37.2 = 148.8m2
For the square base, area is 6 x 6 = 36m2
Total surface area = 148.8 + 36 = 184.8ft2
I am not sure, but this is what I got:
<span>Pipe ALONE = 18 hours
Pipe ALONE in 1 hour = 1/18 of the pool
Hose ALONE in 1 hour = 1/25 of the pool
TOGETHER in 1 HOUR = 1/18 +1/25 = 43/450
TOGETHER they will fill the pool in 450/43 hours
So 5/6 of the pool will take 5/6 X 450/43 = 2250/ 258 = 8.7209302 hours OR
8 hours AND 43.26 minutes ANSWER
