Answer:
528in
Step-by-step explanation:
SA formula: 2Lw + 2Lh + 2hw
for this box: 2(4×10)+2(10×16)+2(4×16)
2(40)+2(160)+2(64)
80+320+128
80+448
<u>528in</u>
a quarter is 1.75 mm thick
1 mm = 0.0393701 inches
0.0393701/12 = 25.4 mm per inch
25.4/1.75 = 14.5 quarters per inch
14.5 x 12 = 174 quarters per foot
174 x 0.25 = 43.50
$43.50 for a foot of quarters
1/2 = 3/6
5 gallons of water changed it to 5/6, so that would mean 2/6 would be 5 gallons worth.
5 x 3 = 15.
Hope this helps.
Just do 11x18x20x14 and u should get it
Y = x^2 cos x
y' = x^2 * -sin x + cos x * 2x
= 2x cos x - x^2 sin x
= x ( 2 cos x - x sin x)
