For this case, we have that by definition:

ρ = \frac {M} {V}

Where:

ro: Density

M: Mass

V: Volume

We find the volume of the pyramid:

V = \frac {1} {3} * l ^ 2 * h

Where:

l ^ 2: Represents the area of the base of the square pyramid

h: Represents the height

So:

V = \frac {1} {3} * (6) ^ 2 * 2.5\\V = \frac {1} {3} * 36 * 2.5\\V = 30 \ in ^ 3

We have to:

M = ρ* V

M = 0.258 \frac {lb} {in ^ 3} * 30 \ in ^ 3\\M = 7.74 \ lb

So, you need 7.74 pounds of zinc

Answer:

7.74 pounds
