a. 29.55 m^2
b. 30.36 m^2
c. 31.25 m^2
D. 28.26 m^2
Answer:
the answer is D
Step-by-step explanation:
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:
Mass = Density × Volume
=3.12 × 10⁻² tons / cubic foot × 4.266 × 10¹⁴ cubic feet
= 1.3309 × 10¹³ tons of water
