feet, and a height of 2 1/4
feet. What is the container’s volume?
A)5 3/5 cubic feet
B)7 1/5 cubic feet
C)12 3/5 cubic feet
D)14 2/5 cubic feet

Answer 1

So,

All we have to do is multiply all three dimensions together.

First, convert all fractions into improper fractions.


`3 (1)/(5)--\ \textgreater \ (16)/(5)`


`1 (3)/(4) --\ \textgreater \ (7)/(4)`


`2 (1)/(4) --\ \textgreater \ (9)/(4)`

Now multiply the fractions together.


`(16)/(5)*(7)/(4)*(9)/(4)= (2*2*2*2*3*3*7)/(2*2*2*2*5)`


`(3*3*7)/(5)--\ \textgreater \ (63)/(5)\ or\ 12 (3)/(5)\ ft.^3`

The correct option is C.
