So the formula for this is for every inch of width, you multiply by 2 to get the length.
Here, I made a table for it.
2×2=4
4×2=8
7×2=14
8×2=16 or 16÷2=8
They would need to buy 5 dozens because the area is 56 and 12 times 5 is 60.
<h3>
Answer: 4.6</h3>
=================================================
Work Shown:
Use the law of sines
b/sin(B) = a/sin(A)
b/sin(62) = 4/sin(50)
b = sin(62)*4/sin(50)
b = 4.61042489526572
b = 4.6
Make sure your calculator is in degree mode.
2 x 2 x 5 = 20
4 x 2 x 2 = 16
20 + 16 = 36
Ans: 36 cubic feet
