The dimensions of the solid given are 10x7x2 units. The

length of the diagonal is

Answer: 12.37 units

Step-by-step explanation:

The dimension supplied can be interpreted as:

Length (L) = 10; width (W) = 7; Height (H) = 2

The dimension supplied gives an insight that the solid is most likely a rectangular box.

The diagonal (d) of the solid (rectangular box) is calculated by:

d^2 = L^2 + W^2 + H^2

d^2 = 10^2 + 7^2 + 2^2

d^2 = 100 + 49 + 4

d^2 = 153

d = √153

d = 12.37 units
