Mitch has a swimming pool in his backyard. The rectangular swimming pool has a volume of 243 m cubed. The length of the pool is 9 m. His neighbor is building a pool with the same dimensions except the length of the pool will only be 3 m. What is the volume of his neighbor's pool?

81

Step-by-step explanation:

Since the question states that the only difference would be the length of the neighbor's pool then this is basically a ratio problem. Therefore, since the question provides 3 values and one variable we can solve this using the Rule of Three which takes the diagonal values multiplies them together, and divides by the last sole value to get calculate the variable like so...

243 volume  <=====>  9 m length

x volume  <=====>  3 m length

(3* 243) / 9 = 81

Therefore, the volume of the neighbors pool will be 81

341

step-by-step explanation:

all you have to do is 9x31 (which equals 279) and then 20x31 (which equals 620). then you have to subtract. 620-279=341.
