Question

there is a tank shape rectangular prism that is 20 by 20 by 16 cm. Amy fills the tank 3/4 of the way, what will be the volume of the water tank???

Answer 1

Find the volume of the rectangular prism by solving the equation V = 20 × 20 × 16.

V = 6,400

Now all you have to do is get 3/4 of that number. For me, it's easier to multiply decimals, so I will change 3/4 into it's decimal form, .75

V = 6,400 × .75 = 4,800.

The volume of the tank is 4,800 cm³.
