3 ( x^8-4v) ........... .
Using the formula given for area:
Area = 1/2 (7 +5)4 = 1/2(12)4 = 24 square cm.
Now to find the volume multiply the area by the depth:
24 x 6 = 144 cubic cm.
The answer is really simple. 3 quarts is more. There are 4 pints in a quart. There are 4 quarts in a gallon.
To write this as a percent, just move the decimal two places to the right. So instead of .098, this becomes 9.8%. hope this helps!
