How do you calculate the area of a rectangular slab?

Multiply the length by the breadth. eg if slab is 2 ft by 3 ft then area of slab = 6 sq feet


How do you calculate the volume of a rectangular slab?

It is length*width*height - in suitable measurement units.


What is the focal length of a rectangular glass slab?

The focal length of a rectangular glass slab is not applicable as it does not have the ability to converge or diverge light to form an image. The primary function of a glass slab is to refract light without focusing it at a specific point.


If you have a slab has a short length of 3m and a long one of 6m do you take as one way slab or tow way slab?

when the length of the slab is more or equal to twice the breadth hence it has to be one way slab.

Why does a light ray incident on a rectangular glass slab immersed in any medium emerges parallel to itself?

When a light ray enters a rectangular glass slab at an angle, it bends towards the normal due to refraction. As it exits the glass slab, it bends away from the normal by the same amount due to refraction again. The angles at which the light ray enters and exits the slab are such that they cancel out the overall deviation, resulting in the emergent ray being parallel to the incident ray.


What is the diameter of a rectangular field of 1km?

A rectangular shape cannot have a diameter, which is a characteristic of a circle.


Cross sectional area of concrete slab?

The cross-sectional area of a concrete slab is the total area of the slab when viewed perpendicular to its length and width. To calculate the cross-sectional area, you multiply the length of the slab by the width of the slab. This measurement is crucial for determining the amount of concrete needed for a project and for ensuring the structural integrity of the slab.


What is lx and ly in one way slab?

ly is the longest span of slab while lx is shortest span of slab


What is the definition of one way slab?

a slab whose length and breadth ratio is more than two is called one way slab


How do you calculate the characteristic length for a rectagular horizantal surface to be be used in correlations for heat transfer coefficent calculation?

The characteristic length for a rectangular horizontal surface is typically calculated using the surface area divided by the perimeter. For a rectangle, the characteristic length ( L_c ) can be defined as ( L_c = \frac{A}{P} ), where ( A ) is the area of the surface (length × width) and ( P ) is the wetted perimeter (2 × (length + width)). This value is used in heat transfer coefficient correlations to represent the effective size of the surface for heat exchange calculations.


Are opposite sides equal in length on a rectangular?

Yes, in a rectangle, opposite sides are equal in length. This is a defining characteristic of rectangles, along with having four right angles. Therefore, if one pair of opposite sides measures a certain length, the other pair will measure the same length.
