Find the surface area of this cube. Be sure to include the correct unit in your answer.
NikAS [45]
Are the dimensions 8yd x 8yd x 8yd? If so this is how you do:

First calculate the area or one side. Then multiply it by 6 as all the sides of the cube have the same area.

Side area = 8yd x 8yd = 64yd^2

Surface area = 6 x 64yd^2 = 384yd^2

Answer:

Add 7 black beads

Step-by-step explanation:

Since we can only change the number of black beads, decide how many black beads you will add based on how many white beads there are.

There are three white beads in the picture.

Total beads we will have (<em>b</em> meaning black)     b : 3

                                  Ratio black : white beads 3 : 1

Use the common ratio, which is a number that both sides of the original ratio multiply by to get to the new ratio.

Find common ratio by dividing total by ratio white beads: 3/1 = 3

Multiply ratio black beads by common ratio. 3 X 3 = 9

<u>We need 9 black beads in total</u>.

Check answer

9 : 3     Both sides divisible by 3; reduce ratio

= 3 : 1        Correct ratio

There will be a total of 9 black beads, but we already have 2 black beads:

(9 total) - (2 original) = (7 to add)

Therefore we need to add 7 black beads.

A woman walks 5 rounds along the border of a square field of area 49². Find the total distance she walks in m.​
Luba_88 [7]
You need to estimate the square root of 200 ft². Rewrite 200 as 2 x 100, then square root of (2*100) is:

10*sqrt(2). The sqrt(2) = 1.414, so the length of each side of the square will be 10*1.414 = 14.14 ft or about 14 ft.
