Abox is shaped like a cube the box has a length of 1 foot a width of 1 foot and a height of 1 foot what’s the volume of the box

1 ft³

Step-by-step explanation:

The formula for the volume of a cube is  

Vol. = l³ = l × l × l

If l = 1 ft,

V = 1 ft × 1 ft × 1 ft

V = 1 ft³

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
