Marianne orders a pack of shipping boxes shaped like cubes. When they arrive, she finds flat pieces of cardboard as shown. What is the least amount of cardboard needed to make each box? Explain how you know.

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
