A prism has a volume of 225 cubic meters. A prism has a length of 7.5 meters, width of w, and height of 5 meters.

Which is the correct substitution for finding the width of the prism?
V = l w h. 225 = 7.5 + w + 5.
V = l w h. 5 = 15 times 225 times h.
V = l w h. 7.5 = 7.5 times w times 5.
V = l w h. 225 = 7.5 times w times 5.

Step-by-step explanation:

Plot the points (observe the figure attached)

Calculate the distance between two points with the formula:

$d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

Substitute the coordinates of the points C and D to calculate the distance CD:

$d_{CD}=\sqrt{(-2-(-3))^2+(4-1)^2}=3.162units$

Substitute the coordinates of the points D and E to calculate the distance DE:

$d_{DE}=\sqrt{(-3-1)^2+(1-0)^2}=4.123units$

Substitute the coordinates of the points E and F to calculate the distance EF:

$d_{EF}=\sqrt{(1-(-1))^2+(0-2)^2}=2.828units$

Substitute the coordinates of the points F and C to calculate the distance FC:

$d_{FC}=\sqrt{(-1-(-2))^2+(2-4)^2}=2.236units$

The perimeter is the sum of the distances. Then:

$P=3.162units+4.123units+2.828units+2.236units\\P=12.35units$

Find the perimeter of a quadrilateral with vertices at c (−2, 4), d (−3, 1), e (1, 0), and f (−1, 2)
