The number of dimensions, a solid has:
(A) 1
(B) 2
(C) 3
(D) 0
(C) 3
Solution:
We know that solid is a three-dimensional object having definite shape, size and volume.
Three-dimensional means that to represent the shape, we need three axes (x, y, z).
The three dimensions of solids are generally known as length, width and height.
For example, a cuboid is a solid with three dimensions as shown:
In case of a cube, we know that length = width = height.
Hence all are called side length.
Solid has three dimensions therefore option (C) is correct.
