Arectangular prism has a volume of 48 ft 3 . if the height of the prism is 4 ft, and the length is 3 feet, what is the width?

6 ft
4 ft
3 ft
2 ft

To be honest on tests if i didnt know the answer i used this one skill. Where i used the answers to figure out the answer* here ill show you how:)
so we know that "Volume = Length x Width x height"
and they only give us the height and length sooo what do we do?
we know that
4 × 3 × W = 48 ft³
so if we didnt know how to figure this out we could plug in A,B,C,and D to find what equals 48ft ³ lets try it:)

a = 6
4 x 3 x 6 = 72
so A cant be the answer 

b = 4 
4 x 3 x 4 = 48
WHAO look we didnt even have to find C and D and we already found the )
so since 4 x 3 x 4 = 48 ft³

THE ANSWER I
B.) 4 ft 
hope this helps 
and don't forget to 
MARK ME BRAINLIEST! :D
