28 We can check this using smaller prisims, with a triangular prism (3-sided) there are 6 vertices. WIth a rectangular prism (4-sided), there are 8 vertices. The number of vertices in a prism is always twice the number of sides.
To create a triangular prism using straws, you would need a minimum of 6 straws. This is because a triangular prism has two triangular faces and three rectangular faces. Each triangular face would require 3 straws, and each rectangular face would require 2 straws. Therefore, the total number of straws needed would be 2 (for the triangular faces) + 3 (for the rectangular faces) = 6 straws.
Without cutting the cubes and using all of them 2 different oblongs can be made: 1 by 6 and 2 by 3.

The volume of water in the rectangular swimming pool can be calculated using the formula for the volume of a rectangular prism, which is length x width x height. In this case, the volume would be 18m x 10m x 2.5m = 450 cubic meters.

Perhaps a rectangular prism
Assuming that the shape of the stadium is a rectangular prism, and using the equation for the area of a rectangular prism (LxWxH=V) you can say that 600x400x100=V 240000x100=V 24000000=V The number of cubic feet that it would take to fill the stadium is 24000000 cubic feet.
Two ways. 1 x 1 x 6 and 1 x 2 x 3. This does not include any other prisms that can be created by merely rotating one of these two. If you include these, there are 9 ways, all defined by some permutation of (1, 1, 6) or (1, 2, 3).
It depends on how accurately you do the measurements in each case.
Take two identical n-sided polygons in parallel planes. Join them together using n rectangular faces. The result will be a right prism.
3 x 3 x 4 = 36 cm3
The formula for finding the surface area of a rectangular prism is 2(wh + lw + lh), where w is width, h is height, and l is length. 3.14 is the value for pi, which is only used for circular objects, like circles, cylinders, and spheres. It has nothing to do with rectangular prisms. Click on the related link below for an illustration of the formula for the surface area of a rectangular prism.
Measure its length, width and height and multiply the three together.
