Answer:
613.5 m^2
Step-by-step explanation:
The area of the base is
A = 1/2 bh
= 1/2 (10) (8.7) =43.5 m^2
We have three sides with all the same area
The area of one side is 10 * 16 = 160
3 * 160 = 480 m^2
Now to the top
We have 3 sides with the same area
The area of one side
A = 1/2 bh
A = 1/2 (10) (6)
= 30 m^2
3* 30 = 90
Add all the areas together to get the total surface area
43.5 m^2+ 480 m^2 + 90 m^2
613.5 m^2

Answer:
77.786 m
Step-by-step explanation:
The shortest length of the rope used cabnbe obtained using trigonometric relation :
Shortest length of the rope = hypotenus
Using the relation :
Cos θ = Adjacent / hypotenus
Adjacent = 50 ;θ = 50°
Cos 50 = 50 / hypotenus
Hypotenus = 50 / cos 50
Hypotenus = 77.786 m
Answer:
that will be 40(wire)-12(rope)=28parts
Step-by-step explanation:
6meter wire div by 0.15 eq to 40
3meter rope div 0.25 eq to 12
so we use 40-12=28parts
