HELP ME PLSS and thannks

is 72 square cm

Step-by-step explanation:

and don't forget to put the little 2 up on the m on cm or sometimes it's square cm

72 cm^2 (Squared aka the tiny 2 up top)

Step-by-step explanation: I will start with 6x2. On the right side you see 6 and 2. The area of that is 6x2 = 12 and since it is also on the other side even though it doesn't say it, you just multiply by 2 12x2 = 24. Just do that with every side. 3x2 = 6, 6x2 = 12. 3x6 = 18, 18x2 = 36.

Add all of the answers up 24+12+36 = 72

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.
