How can we find the volume of this fish tank? i needed but good

Find the number of 1-foot cubes that fill the fish tank

Volume of a cuboid such as the fish tank is given by the product of length width and height;

Such that; Volume = length × width × height

Similarly, we can count the number of 1 foot cube that can fill the fish tank.

And since each cube has a volume of 1 cubic ft, then the number of cubes will be equivalent to the volume of the fish tank in cubic ft.

the first point, i am pretty sure.
