Find the surface arew of a cube with a side length of 8 yards

384 yards squared

Step-by-step explanation:

since a cube is made of of 6 faces, and each faces are squares, the area of a square is s^2.

Since the surface area of a cube is the area of a square times the number of sides, the equation 8^2 x 6 can be set up.

So the answer is 384 yards^2

SA = 2LW + 2LH + 2WH

SA = 2(8x8 + 8x8 + 8x8)

SA = 384

13

step-by-step explanation:

169-1=168

168-3=165

165-5=160

160-7=153

153-9=144

144-11=133

133-13=120

120-15=105

105-17=88

88-19=69

69-21=48

48-23=25

25-25=0

since it took 13times to completely subtract it hence its square root is 13

  y= -3x is the required function.

step-by-step explanation:

we have been given a table:

x             y

0             0

1             -3

3             -9

-2             6

we can see that the values of y is -3 times the value of x

hence, the function would be: y= -3x.

put the values of x will give the same y as in the table that means function is satisfying the given table.
