What shape is a brick?

Hint: Draw a common brick, which we usually use. Now mark length, breadth and height for the brick you have drawn. Compare the drawn figure with different geometrical shapes like cube, cuboid, rectangle etc and find the shape of brick.

Complete step-by-step answer:
We need to find the shape of a brick. Let us draw a brick first. From the figure, we can see that the brick represents a cuboid.

Here l, b and h represents length, breadth and height of the cuboid i.e. the brick.
We can place a common brick in either way as shown in the figure.

We know that a cuboid is a three – dimensional structure having 6 rectangular faces. There six faces of the cuboid exist as a pair of three parallel faces. When the area of the faces of a cuboid is the same we call this cuboid as a cube.
Thus we figured out that the shape of the brick is a cuboid.
To find the surface area of the cuboid, you can use the formula,
Surface area of cuboid = 2 (lb + hb + lh)
Similarly, the volume of cuboid = V = lbh

Note: Bricks have various shapes. The most common is the cuboid shaped brick which we have taken. There may be variations in the dimensions of the brick according to the brick type, you have chosen.
