Find the volume.

1. 2ft, 4ft, 5ft
V=

2. 4cm, 4cm, 9cm
v=

3. 6in, 6in, 6in
V=

4. 4ft, 12ft, 4ft
V=

I need help on the above and do not know where to begin. Please help

To find the volume, multiply the length times the width times the height.

1. V = 40 cubic feet

To find the volume for each of the given dimensions, we need to use the formula for the volume of a shape. The exact formula will depend on the shape of the object, so let's determine the shape for each set of dimensions.

1. The dimensions provided (2ft, 4ft, 5ft) do not correspond to a specific shape. Are you trying to find the volume of a rectangular prism, a cylinder, or some other shape? Once you determine the shape, you can use the appropriate formula to calculate the volume.

2. Similarly, the dimensions (4cm, 4cm, 9cm) do not specify a particular shape. Please clarify which shape you are referring to so that we can proceed with calculating the volume.

3. In this case, the dimensions (6in, 6in, 6in) are all equal, which indicates a cube. The volume of a cube is calculated by cubing the length of one side. So, for this cube, the volume would be (6in)^3 = 6in x 6in x 6in = 216 cubic inches.

4. Once again, the dimensions provided (4ft, 12ft, 4ft) do not specify a shape. Please let me know which shape you are referring to, and we can continue with finding the volume.

To correctly find the volume, it is crucial to determine the shape of the object. Please provide more information, or specify the shape, so that I can assist you further.
