Here is the complete 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 $14dollar sign, 14 per cubic meter. How much will it cost to completely fill the box with hay?
Answer:
it cost $42 to completely fill the box with hay
Step-by-step explanation:
Given that :
The length of the wooden box = 3m ; the width of the box = 1m and the height of the box = 1 m; we can easily determine the volume of the rectangular wooden box;
We all know it would assume the shape of a rectangular prism and it's volume = L × W × H
Thus; the volume of the box = . 3 m × 1 m × 1 m = 3 m³
However, the question proceeds by stating it that the wooden box cost $14 per cubic meter;
So , if 1 cubic meter = $14;
three cubic meters = $14 × 3 = $42
Hence; it cost $42 to completely fill the box with hay
