Plzz i will mark brainiest and and 5 stars if right what is the surface area of the cube? drag and drop the correct surface area to match the cube. cube with edge length = 3.2 m a.12.8 m² b.19.2 m² c.51.2 m² d.61.44 m²

1; 35 is the ratio

step-by-step explanation:

54 kilometers per hour

step-by-step explanation:

according to rules:

1 km = 1000 meter

which means that 1 meter = 1/1000 km

1 hour = 3600 second [ as 1 hour = 60 min = 60 *60 seconds ]

which means that 1 second = 1/3600 hour

therefore, 1 kilometer/hour =

thus to convert 15 meter per second to kilometer per hour, we multiply 15 to 3.6 kilometer/hour.

15 meter/second=   which is the required answer.
