A length of a metal bar has a cross sectional square of 12cm. If the length is 2m, what is the volume of the metal bar in cm3?
Lillie, is your question written correctly?
/ /
2m / /
/ / 2m x12cm x 12cm = volume
/ / =>200cm x12cm x 12cm= volume
12cm[___} =>200cmx12cm x 12cm= __cm3
12cm =>(200x12x12)cm3
=> 28,800 cm3
Sorry, I drew the picture and it didn't show it.
So, it is 2 meters converted to 200 cm times 12 cm times 12 cm to figure the volume.
volume = 12(12)(200) cm^3
= 28800 cm^3
or
.12(.12)(2) m^3
= .0288 m^3
To find the volume of the metal bar, we need to multiply the cross-sectional area by the length of the bar.
First, let's convert the length from meters to centimeters.
1 meter = 100 centimeters
So, the length of the bar in centimeters is:
2 meters x 100 centimeters/meter = 200 centimeters
Now, we can calculate the volume.
The cross-sectional area of the bar is given as a square with dimensions 12 cm x 12 cm = 144 cm².
To find the volume in cm³, we multiply the cross-sectional area by the length:
Volume = Cross-sectional area x Length
= 144 cm² x 200 cm
= 28,800 cm³
Therefore, the volume of the metal bar is 28,800 cm³.
