Answer:
![d=3.75\ \text{tons per cubic meter}](https://tex.z-dn.net/?f=d%3D3.75%5C%20%5Ctext%7Btons%20per%20cubic%20meter%7D)
Step-by-step explanation:
Given that,
Mass of a certain material, m = 71 pounds
Since, 1 ton = 2000 pounds
71 pounds = 0.0355 ton
Volume of the material, V = 2.5 gallons
Since, 1 m³ = 264.172 gallon
2.5 gallon = (2.5/264.172 ) m³
Density,
![d=\dfrac{m}{V}\\\\d=\dfrac{0.0355\ \text{tons}}{\dfrac{2.5}{264.172}\ m^3}\\\\d=3.75\ \text{tons per cubic meter}](https://tex.z-dn.net/?f=d%3D%5Cdfrac%7Bm%7D%7BV%7D%5C%5C%5C%5Cd%3D%5Cdfrac%7B0.0355%5C%20%5Ctext%7Btons%7D%7D%7B%5Cdfrac%7B2.5%7D%7B264.172%7D%5C%20m%5E3%7D%5C%5C%5C%5Cd%3D3.75%5C%20%5Ctext%7Btons%20per%20cubic%20meter%7D)
Multiply the amount of book Robin read by 1/2.
3/4 x 1/2 = 3/8
Mark read 3/8 of the book.
