What is the surface area of the triangular prism?
5 ft
14 ft
9 ft
6 ft
24
square feet

168 ft^2

Step-by-step explanation:

Surface Area = 2 * [h*b/2 + l*s] + bl

= 2 * [4ft*6ft/2 + 9ft*5ft] + 9ft*6ft

= 168 ft^2

since the airplane is moving with constant speed then the distance travelled can be calculated by x=u*t

in km/h would be:

x=640*3.5=2.240 km

in m/s would be:

u=640 km/h= 640.000 m/h =640.000/ 3600 m/s =177.8 m/s

t= 3.5 h= 3.5 * 3600 s=12.600 s

then x=u*t= 177.8*12.600= 2.240.280 m
