A water tank measures 5 in. by 10 in. by 7 in. If each dimension of the tank were doubled, approximately how many more gallons can the larger tank hold? (Hint : There are 231 cubic inches in 1 gallon.)

A: The large tank holds about 2,450 gal more water than the small tank.
B: The large tank holds about 10 gal more water than the small tank.
C: The large tank holds about 22 gal more water than the small tank.
D: The large tank holds about 16 gal more water than the small tank.

Answer 1

10

Explanation:

you should go by this; 5x10x7=350 which can round up to two gallons. then you do 350 x 2 to the third power, which should be 350x8=2800. which 2800 rounds to 12 gallons, so then you do 12-2=10. So 10 would be the answer! Hope this helped!!
