Write an equation for the statement and then solve the equation.
The width of a rectangular rectangular prism is 30 cm. This is
12 more than one-fourth of the length. Find the
volume of the prism, given the height is 20 cm.
16. Equation:

17. Volume:

16.   30 * (30+12)/4*(L)*20

17.  Volume = 6300 * Length of rectangular prism

Step-by-step explanation:

The width of a rectangular prism is 30 cm. This is  12 more than one-fourth of the length. Find the  volume of the prism, given the height is 20 cm.

Let L = length of rectangular prisim W = width and H = height

16.  

Volume of a rectangular prism is width * length * height

30 * (30+12)/4*(L)*20

17.  

= 30 * (30+12)1/4(L)*20

= 30 * (42/4)*L * 20

= 600 * 10.5 * L

= 6300 * L

Volume = 6300 * Length of rectangular prism

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2
