Cage

How many m2 of mesh farmer use for fencing of a cuboid cage with dimensions 25m, 18m, and 2.5m?

Result

S =  665 m2

Solution:

a=25 m b=18 m c=2.5 m  S=a b+2 (a+b) c=25 18+2 (25+18) 2.5=665 m2a=25 \ \text{m} \ \\ b=18 \ \text{m} \ \\ c=2.5 \ \text{m} \ \\ \ \\ S=a \cdot \ b + 2 \cdot \ (a+b) \cdot \ c=25 \cdot \ 18 + 2 \cdot \ (25+18) \cdot \ 2.5=665 \ \text{m}^2



Our examples were largely sent or created by pupils and students themselves. Therefore, we would be pleased if you could send us any errors you found, spelling mistakes, or rephasing the example. Thank you!
