Question

An open-topped fish tank has a length of 30 inches, width of 10 1/2 inches, and height of 12 inches. What is the volume of the water in the tank if the tank is 3/4 filled?

A 945 in
B. 1,287 in
C. 2,835 in
D. 3,780 in​

Answer 1

2835 inches cubed

Step-by-step explanation: Volume equals all three sides multiplied by each other so 30*12*10.5=3780 in. However because the tank is only 3/4 full you multiply 3780 by 3/4 to get 2835.
