Juanita is packing a box that is shaped like a rectangular prism.The box is 18 inches long and 9 inches tall.the total volume of the box is 1,944 cubic inches.use the formula V=lwh to find the width of the box.show work.PLEASE HElP!
How did you get the width?
1,944 = 18 * w * 9
1,944 = 162w
1,944/162 = w
? = w
I still don't understand Ms.Sue,can you please explain a little easier,where do the l and h come in at,im only in 5th grade,math is hard for me
L = length = 18 inches
H = height = 9 inches
thank you Ms.Sue
You're welcome, Zion.
Volume =L×W×H
Volume 1944=18×9×W
1944=162×W
W=1944÷162
W=12
Width is 12
Now 12×18×9=1944.
12x18x9=1944
To find the width of the box, we can rearrange the formula V = lwh to solve for the width (w).
Given information:
Length (l) = 18 inches
Height (h) = 9 inches
Volume (V) = 1,944 cubic inches
Substituting the known values into the formula, we have:
1,944 = 18w * 9
Now, let's solve for w by isolating it on one side of the equation.
First, divide both sides of the equation by (18 * 9):
1,944 / (18 * 9) = w
Performing the calculation:
1,944 / 162 = w
12 = w
So, the width of the box is 12 inches.
