Question

12” x 14” x 20” = _________________________cubic feet (cbf

to nearest tenth

Just cancel all its taking too long

Answer 1

1.9

Explanation:

Hello

in order to perform the conversion we must know

1"=1 inch

12 inch = 1 feet

step 1

convert and make the product

`12in((1\ feet)/( 12in))=1 feet \\12 in=1 feet\\\\14in((1\ feet)/( 12in))=(7)/(6)feet \\ 14in=(7)/(6)feet \\\\20in((1\ feet)/( 12in))=(5)/(3)feet \\14in=(5)/(3)feet\\\\V=1ft*(7)/(6) ft * (5)/(3)ft =1.944 ft^(3)\\`

answer 1.944 cbf

Now, let's make the product and then the conversion

`12in*14in*20in =3360 in^(3)`

`3360 in^(3)*((1 feet)^(3) )/((12 in)^(3) )=\\3360 in^(3)*((1 feet^(3)) )/((1728 in^(3)) ) =\\ \\1.94 \ cbf`

I hope it helps
