Answer:
Constanza ocupará, como mínimo, para forrar la caja:
1350 cm²
para forrar la caja
Step-by-step explanation:
En un cubo cada una de las aristas que lo conforman miden lo mismo.
Un cubo tiene 6 caras.
La formula del área del área de las 6 caras del cubo es:
área total del cubo = a = 6*arista²
en este caso:
a = 6*(15cm)²
a = 6 * 225 cm²
a = 1350 cm²
Answer:
-6
Step-by-step explanation:
A(n)=-6+(1-1)(1)
simplified, this equals:
A(n) = -6+(0)(1)
A(n)=-6+0
A(n) = -6, for any given n term.
Answer:
$3.45
Step-by-step explanation:
17.25 divided by 5 is equal to 3.45
![3 \sqrt{729}](https://tex.z-dn.net/?f=3%20%5Csqrt%7B729%7D%20)
The square root of 729 is in fact 27, as it is a perfect square, but this is not well known, so we can figure it out like this:
What goes into 729 that are perfect squares? 81 and 9:
![3 \sqrt{81*9}](https://tex.z-dn.net/?f=3%20%5Csqrt%7B81%2A9%7D%20)
Take the square root of 81 (9) and the square root of 9 (3). Move these to the outside of the square root (they will multiply with 3 since 3 is multiplied to the square root in the original problem)
![3 \sqrt{81*9} \\ 3*9*3](https://tex.z-dn.net/?f=3%20%5Csqrt%7B81%2A9%7D%20%5C%5C%203%2A9%2A3)
Now, just multiply:
It’s 97.39
The equation to find the circumference is ( C=2πR )
