Use a tape measure or ruler. ;)
The surface of a rectangular prism would be 60 yards. This is use in math.

If the base is a rectangle, use the formula for the area of a rectangle.
Although there is a separate formula for it, yes, a cube is technically a rectangular prism, and you can use the rectangular prism's formula, because a rectangle is defined as a quadrilateral with four right angles, which a square is.
To make a Rectangular Prism you should follow this 4 steps: 1) Draw a net for a rectangular Prism, including dimensions and glue flaps. 2) If you want you can name them (front, back, top, bottom, left side and right side) to make it easy for you. 3) Cut out your net, Dry fold, (fold it but don't glue the flaps), to be sure that it works. 4) If you are happy about the Rectangular Prism and it works then use glue or adhesive tape and glue it together (The best thing is to use adhesive tape so that it sticks properly). You should now have your Rectangular Prism made.

bcoz in triangular prism, sides are not parallel so rays will deflect but in rectangular prism sides are parallel so rays won't deflect instead they will pass straight.

A rectangular pyramid you use 1/3 or divide 3 in the product but a triangular prism you use 1/2 or divide 2 on the product.

Use this formula:Volume = (length) x (width) x (height)
If the base is a rectangle, use the formula for the area of a rectangle.

The answer will depend on what is known about the rectangular prism. If you have no measurements then the only way to obtain the height is to measure it - either directly or indirectly. If you know three out of its length, breadth, volume and total surface area it is possible to use the formulae connecting them to calculate the height. Instead of the volume, you could have the mass and knowledge of the substance that a solid prism is made out of. In each case, a different formula is required.
