Asolid gold cube with edge of 2" is melted down and recast as a cone with a 3" radius base. find the height of the cone. 8/(9) 2 8/(3)

The height of the cone is

Step-by-step explanation:

step 1

Find the volume of the cube

The volume of a cube is equal to

where

b is the length side of the cube

we have

substitute

step 2

Find the height of the cone

The volume of the cone is equal to

we have

-----> the volume of the cone is equal to the volume of the cube

substitute the values and solve for h

a box 3 3/4 feet long or 4+ feet.

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.
