Please help. Will mark brainliest!

the volume would be 384 but if you want it separately it would 8*4= 32

8*12=96

4*12=48

but the total cost would be 176 after you add up the equations

and the surface area would be 352

hope this helped :D

It is 384 is for volume and  352 for surface area

Step-by-step explanation: 384 square inches for volume because you multiply all the numbers together.  V = LWH (volume=lengh+with+hight)

352 for surface area.

V = (8) x (4) x (12)

V = 384 inches squared

SA = 2(LH)+2(LW)+2(WH)

SA = 2(8x12) + 2(8x4) + 2(4x12)

SA = 192 + 64 + 96

SA = 348 inches squared

I hope this helps! =3

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
