the u. s post office will accept a box for shipment only if the sum of the length and girth (distance around) is at most 108 inches. Find the dimensions of the largest acceptable box with

The dimension of the largest acceptable box

Step-by-step explanation:

Let length of box,l=x

Side of square base=y

We are given that

x+4y=108

Now, volume of box,V=

y=0 is not possible

Therefore, y=18

Hence, the volume of box is maximum when y=18

Now,

Hence, the dimension of the largest acceptable box

the anwser is d) 75°

step-by-step explanation:

54 km / hours

step-by-step explanation:

we need to convert seconds to hours

60 seconds = 1 minutes

60 minutes = 1hour

15 m         60 second   60 minutes

  * *         = 54000 meters/ hour

second     1 minute             1 hour

now we need to convert meters to km

1000 m = 1 km

54000 m       1 km

*   = 54 km / hours

hour               1000m
