# Question how much gravel would be required to fill an area t

Question

how much gravel would be required to fill an area that you would like to landscape.
1. If the measurement of the lab�s are width=787.4 cm, length=1059.18 cm, and height=332.74 cm
2. Determine the density of a sample of pea gravel. The determination should be of a representative sample (i.e. 35-40 pea gravel particles). Make at least three independent measurements (on different samples) and average the measurements to get more representative data. (See data table below).
3. Estimate the total volume of gravel you would need to buy to completely fill the lab room from the floor to the bottom of the cement ceiling �rafters�. We will assume that all of the lab benches, hoods, and utility pipes will be removed before starting the project.
4. Calculate the total mass of gravel required to fill the room (in grams and metric tons)
5. Calculate total number of individual pieces of gravel required to fill the room.
6. Calculate how many moles of pea gravel you would need to fill the room.
Also you have to answer: 1. A very brief description of how you determined the density of the pea-gravel.
2. A brief description on how this experiment changed (or not) your understanding of the mole concept.

Be certain that you have examined each of the answers for reasonableness (e.g., if 13 m3 of pea gravel are required to fill the lab room, a mass of 15 g is unreasonably low).
