Answer: 33.6 min
Step-by-step explanation:
Volume = L*W*H = 9 * 13 * 14 = 1638 in^3
Vol2 = 21 * 25 *35 = 18375 in^3
18375/1638 = 11.2 times bigger, so 3min * 11.2 = 33.6 minutes
1/4 (8x+3) ⇒ 1/4×8x = 2x +3
Not completely sure what you are asking, but the area of a square with the side lengths of 230m would be 230*230=52,900.
