Question

A Glass Paper Weight is in the shape of a pyramid with a square base of 6cm and a height of 7cm. Given that the density of the glass is 3.1g/cm3, find the mass of four identical paper weights.​

Answer 1

Answer:

1041 gm

Step-by-step explanation:

denisty =mass/volume

We know the density is 3.1gm/cm^3

Find out Volume:

V=$\frac{1}{3}*baseArea*height$

V=$\frac{1}{3}*(6)^{2} *7$

V=84

Now for mass:

mass=density * volume

mass = 3.1 * 84

mass of one glass weight = 260.4

mass of 4 identical paper weights = 260.4*4

=1041 gm
