Given:
Consider the dimensions of a rectangular prism are 4 in by 3 in by 10 in.
To find:
The length of the diagonal.
Solution:
Length of diagonal of a rectangular prism is:

Where l is length, b is breadth and h is height.
The dimensions of a rectangular prism are 4 in by 3 in by 10 in. So, the length of diagonal of the rectangular prism is:




Approximate the value to the nearest tenth.
