Answer: 54000 cube cm
Step-by-step explanation:
Let h be the height of the box kite,
Also the length of one face = 30 cm,
Hence, the total area of the kite box that is covered by the fabric
= 4 × Area of one face
= 4 × 30 × h
= 120 h
According to the question,
120 h = 7200
h = 60 cm
Hence, the height of the box = 60 cm,
The volume inside the kite = The base area of the box × Its height
= 30² × 60
= 900 × 60
= 54000 cm³
Answer:
Step-by-step explanation:
Length of the bridge = 190 m = 190*100 = 19000 cm {100cm = 1m}
Length of each pace of Robert = 80 cm
Minimum number of full paces = 19000/80
= 237.5
= 238 {because full paces}
Answer:
The total cost of resurface the path is 
Step-by-step explanation:
step 1
Find the area of the path
The area of the path is equal to the area of the path plus the swimming pool minus the area of the swimming pool



step 2
Find the cost of resurface the path
Multiply the area of the path by $2 per square foot

First of all, we know a quality of all interior angles of a triangle, they should add to 180 degrees.
Does 50+50+80 degrees give 180 degrees?
100+80=180 degrees
Therefore, yes, it is possible to draw a triangle with the angle measures given to be 50, 50 and 80 degrees.
Hope I helped :)
