thx so much!! this is perfect

You're very welcome. :-)

the answer is lwh

-2(-2)^2

To find the formula for the volume of a rectangular prism, follow these steps:

Step 1: Identify the dimensions of the prism. Typically, a rectangular prism has three dimensions: length (L), width (W), and height (H).

Step 2: Once you have the dimensions, use the formula: Volume = Length × Width × Height.
Alternatively, you can also represent it as V = L * W * H.

For example, if the length of a rectangular prism is 5 units, the width is 3 units, and the height is 4 units, the volume would be:
V = 5 × 3 × 4 = 60 cubic units.

Now, let's move on to the formula for the volume of a cylinder.

To find the formula for the volume of a cylinder, you can follow these steps:

Step 1: Identify the dimensions of the cylinder. A cylinder has two dimensions: radius (r) and height (h).

Step 2: Once you have the dimensions, use the formula: Volume = π × (radius^2) × height.
Alternatively, you can also represent it as V = πr^2h, where π (pi) is a mathematical constant approximately equal to 3.14159.

For example, if the radius of a cylinder is 2 units and the height is 7 units, the volume would be:
V = π × (2^2) × 7 = 28π cubic units.
