Question

Steve has a fish tank shaped as a rectangular prism that has a height of 21 cm, a length of 17

cm, and a width of 12 cm. If Steve leaves 4 cm of space without water, what is the volume of

the water he does put in the tank?

Answer 1

To find the volume of water, we must find the volume of the tank. The volume of a rectangular prism is found by multiplying together the length, height, and width: V=lwh

"4 cm of space without water" means that the water will not fill the whole tank, however, but end four cm before the top. We must therefore subtract 4 cm from the height before we find the volume.

21-4=17 Our new height is 17. We can now use the Volume formula: V=17*12*17

V=3468 cm squared

If I remember my metric training correctly, that's 3.468 liters.

Answer 2

V = (17)(17)(12) The first 17 is 21 - 4
