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
