Find the total surface area of this cuboid.
Height=4.8
Width=3.1 cm
Length=7.2 cm

Step-by-step explanation:

At = 2*(h×w + h×l + w×l)

= 2*(4.8×3.1 + 4.8×7.2 + 3.1×7.2)

= 2*(14.88 + 34.56 + 22.32)

= 2*71.76

= 143.52 cm²

the image of (6, 9) under a dilation is (4, 6). the scale factor is

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.
