The volume of the rectangle has been given by the product of length, breadth, and height. The mass of the air with a density of 1180 g/m³ is 708.57 gms.
<h3>What is density?</h3>
The density of the substance has been known to be given by the mass's ratio to the volume. The formula for density is given as,
Density = Mass ÷ Volume
Given,
Density = 1180 g/m³
The volume of the rectangle = L×B×H
Substituting the values above,
Mass = Density × Volume
M = 1180 × 1.2 × 10⁻² × 8.34 × 10¹ × 6.0 × 10⁻¹
= 708.57 gm
Therefore, the mass of the air is 708.57 gms.

Option c. dendrochronology
tree rings or dendrochronology they allow to use it in calibration for carbon-14 on temporal placements of fragments of wood (from long dead trees).

Thomson in 1897 was the first to suggest that one of the fundamental units was more than 1,000 times smaller than an atom, suggesting the subatomic particle now known as the electron. Thomson discovered this through his explorations on the properties of cathode rays.
Try c I think is the most accurate one
Density = mass / volume so mass = density x volume. Therefore mass = 2.70 x 348 = 939.6g
