In this case, we'll have to carry out several steps to find the solution.

Step 01:

Data

rectangular prism

l = 8 mm

w = 6 mm

h = 5 mm

length of the diagonal = ?

Step 02:

l = 8 mm

w = 6 mm

h = 5 mm


\text{diagonal = }\sqrt[]{l^2+w^2+h^2}
\text{diagonal = }\sqrt[]{(8\operatorname{mm})^2+(6\operatorname{mm})^2+(5\operatorname{mm})^2}
\text{diagonal = }\sqrt[]{125\operatorname{mm}}^2

The answer is:

The length of the diagonal is √125 mm²
