( 199-47)/2

= 152/2

=76 (pieces)

A: Korea won 76 gold medals.

(2) Bus departure station, bus No.8 10 minute, bus No.26 15 minute. The two buses leave at the same time at 5: 30 in the morning. When will the next two buses leave at the same time?

( 10、 15)=5*2**3=30

5:00+0:30=6:00

A: The next time two cars leave at the same time is 6 o'clock.

(3) As shown in the figure on the right, there is a sealed glass container with a length of 20dm, a width of 8dm and a height of 10dm.

(1) How many pieces of glass does it take to make this glass container?

(20*8+20* 10+8* 10)*2

=( 160+200+80)*2

=440*2

=880(dm？ )

Does it take at least 880 microns to make this glass container? Glass.

② The water depth in the container is 4dm. If it is erected with the smallest surface as the bottom, what is the water depth?

20*8*4

= 160*4

=640 (mark? )

10*8=80(dm？ )

640/80=8 Deutsche Mark

A: the water depth is 8dm.

(4) There is a parallelogram lawn (as shown on the right). If a fence is to be placed around it, what is the total length of the fence?

(60+40)*2

= 100*2

=200 meters

A: The total length of the fence is 200 meters.
