Answer:
761 cubic feet.
Step-by-step explanation:
Your neighbor also has a swimming pool of the same shape as yours, but it is 75% the depth.
Then, if my swimming pool's depth is H, then my neighbor's pool will have depth .
So, if my swimming pool has dimensions L ft. by W ft. by H ft., then my neighbor's pool will have dimensions L ft by W ft. by 0.75H ft.
Now, given that the volume of my pool is 1015 cubic ft.
So, LWH = 1015 ......... (1)
Now, my neighbor's pool has volume V = 0.75LWH = 0.75(1015) = 761.25 cubic ft ≈ 761 cubic ft. {Round to the nearest whole number} (Answer)
{From equation (1)}
Percent error=|

(note the || is absolute value, means that whatever the result is inside, it is made positive)
predicted value=261
actual value=293

|-0.12|
absolute value
0.1226
time 100
0.1226 times 100=12.26
answer is 12.26%
