Harriet needs to ship a small vase. the box she will use has a volume of 216 cubic inches. if the side lengths are all the same, what is the length of each side of the box? hint: v =

The box has a shape of cube. The volume of cube with side s in is

Since Harriet uses a box of volume 216 cubic inches, then

and, therefore,

Note that then

the length of each side of the box is 6 inches.

step-by-step explanation:

given perimeter: 28cm

length: 9cm

atp,

2(l+w)=p of the reactangle

2(9+x)=28

18+2x=28

2x=28-18

x=10/2

x=5

therefore width is 5 cm

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.
