Question

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

Answer 1

Answer:

1.9

Step-by-step 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

$12in(\frac{1\ feet}{ 12in})=1 feet \\12 in=1 feet\\\\14in(\frac{1\ feet}{ 12in})=\frac{7}{6}feet \\ 14in=\frac{7}{6}feet \\\\20in(\frac{1\ feet}{ 12in})=\frac{5}{3}feet \\14in=\frac{5}{3}feet\\\\V=1ft*\frac{7}{6} ft * \frac{5}{3}ft =1.944 ft^{3}$

answer 1.944 cbf

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

$12in*14in*20in =3360 in^{3}$

$3360 in^{3}*\frac{(1 feet)^{3} }{(12 in)^{3} }=\\3360 in^{3}*\frac{(1 feet^{3}) }{(1728 in^{3}) } =\\ \\1.94 \ cbf$

I hope it helps
