Mass of water in the lake is 1.3309 × 10¹³ tons.
Step-by-step explanation:
Density is defined as mass divided by volume.
Given:
Density of water, d = 3.12 × 10⁻² tons / cubic foot
Volume of the lake, v = 4.266 × 10¹⁴ cubic feet
Mass of the water in tons, m = ?
Formula to be used:
[tex]$d = \frac{m}{V}[/tex]
Mass = Density × Volume
= 3.12 × 10⁻² tons / cubic foot × 4.266 × 10¹⁴ cubic feet
= 1.3309 × 10¹³ tons of water
