Answer:

Step-by-step explanation:

there are 6 sides on a cube

surface area = 6 times the area of one face of the cube

= 6 times ( a side times another side) note all sides are equal

= 6(side)² is a side equal to 2/3 ?? if it is ....

= 6(2/3)²

= 6(2/3)(2/3) one of the 3s divide into 6 twice

= 2(2)(2/3)

= 2³ / 3

= 2x2x2 / 3

= 8 /3

= 2 and 2/3 units²

Sophia uses 18 beads to make a necklace. Three sixths of the beads are purple. How many beads are purple?

tatuchka [14]

Answer:

9 beads are purple

Step-by-step explanation:

we know that

To find out how many beads are purple, multiply the total beads by the fraction of the beads that are purple

$18(\frac{3}{6})=9\ beads$

therefore

9 beads are purple

Another way to solve the problem is convert the fraction in percentage

we have

$\frac{3}{6}=\frac{1}{2}=0.50*100=50\%$

If the total are 18 beads

50% is 9 beads

therefore

9 beads are purple
