Can someone find the surface area of the picture below.

The area of each of the 4 triangles is

... A = (1/2)bh = (1/2)(4)(3) = 6

The area of the square base (in the center of the net diagram) is

... A = s² = 4² = 16

Then the total area is 4×6 + 16 = 40 square units.

1.4

2.3

step-by-step explanation:

the formula for the constant of variation is

y= kx

divide each side by x

y/x =kx/x

y/x =k

we know a and y

1.   y/x = k

4/1 =4

check the other values to make sure they are the same

8/2 = 4   12/3 =4   and 16/4 =4  

the constant of variation is 4

2.   y/x = k

3/1 =3

check the other values to make sure they are the same

6/2 = 3   9/3 =3   and 12/4 =3  

the constant of variation is 3
