A cube is shown.<br><br> What is the surface area of the cube?
valkas [14]

1350 cm^2.  First, we must find the area of one side.  The formula for the area of a square is S^2 or S*S, so plugging in the value of the side we get 15*15=225.  So each side of the cube is 225 cm^2, so since there are 6 sides, we just multiply by 6 (225*6=1350).

A rectangular soccer field is 80 meters wide and 110 meters long. The coach asks players to run from one corner of the field to
seraphim [82]

Answer:

Step-by-step explanation:

Goven the length of the field = 110m

Width = 80m

The length of the diagonal is expressed using the pythagoras theorem;

d² = l² + w²

d² = 110² + 80²

d² = 12100 + 6400

d² = 18500

d = √18500

d = 136.01

Hence the players have to run 136.01m diagonally

A game field is 360 feet long. The practice field is 2/5 shorter than the practice field. How long is the game field?feet
vlabodo [156]

Answer:

The practice field is 144 feet long.

Step-by-step explanation:

360 x 2/5 = 144

(You would multiply these numbers NOT divide!)

To check my math:

2/5 = 0.4

144/360 = 0.4

By doing the above check, I know the two equations are the same. By seeing this I can know that the answer is correct.
