3. Leo made a container to store his camping gear. The container is in the shape of a rectangular prism. The container has material covering all six sides.

(a) What is the capacity of the container? (Volume)
(b) How much material was used to make the container? (Surface Area)

A is 40ft3

B is 76ft3

Step-by-step explanation:

A is Volume. V= LxWxH

V=5 x 2 x 4

V= 40ft3

B is surface Area. 5x2= 10

2x4=8

4x5=20

10+8+20=38

38x2= 76ft3

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

7.25

step-by-step explanation:

we know that 7 equals to 7.0. we also know that 1/4=0.25. so we can add the two together and we get 7.25
