Question

Erin built a wooden box to hold hay on her farm. The box is 3 \text { m}3 m3, start text, space, m, end text long, 1 \text { m}1 m1, start text, space, m, end text wide, and 1 \text { m}1 m1, start text, space, m, end text high. Hay costs \$14$14dollar sign, 14 per cubic meter. How much will it cost to completely fill the box with hay?

Answer 1

$42

Explanation:

• Length of the Box =3m
• Width of the box =1m
• Height of the box=1m

Volume of a Rectangular Prism =LWH

Therefore, Volume of the Box =3*1*1=3 cubic meters

Now, Hay costs $14 per cubic meter.

Therefore, cost of filling the box = Volume X Cost per cubic meter

=3 X $14

=$42

It would cost $42 to fill the box completely with hay.
