Answer:

A. The volume is 1428

B. Yes, Riley is incorrect, the volume will not triple if the measurements are tripled.

Step-by-step explanation:

A. 16*8.5*10.5= 1428 (Volume of the aquarium)

B. The reason for that is :

  1. 16*3 = 48
  2. 8.5*3 = 25.5
  3. 10.5*3 = 31.5

If you multiply these numbers together you don't get the triple of the previous volume (1428).

In fact, you get 38556, which is more than triple of 1428.

Answer:

a. 1428   b. no

Step-by-step explanation:

a. 16*8.5*10.5=4*17*21=84*17=1428.   16 is made into 4, and 2 is multiplied to 8.5 to get 17, and 2 is also multiplied into 10.5 to get 21. The multiplication part is easy.

b. using 4, 17, and 21, the new dimensions are 12, 51, and 63. Again, easy multiplication. The product, 38556, is 27 times greater than 1428.
