When you multiple a whole you just multiple straight across when you multiple a decimal you you go from right to left starting with the first number on the right then go to the top next then the next then take the next number on the bottom and do the same thing

Alexis wants to make a paperweight at pottery class. He designs a pyramid-like mode l with a base area of 100 square centimeters

olga55 [171]

Answer:

$\frac{3}{2}$ g/cm²

Step-by-step explanation:

First, we need to find the volume of the prism. The volume of a square pyramid is V = Bh/3

B = 100 cm²

h = 6 cm

V = 100 cm² * 6 cm /3

V = 600 cm³ /3

V = 200 cm³

Next, we need to solve for the density based on the desired volume and mass.

m = mass = 300 g

V = volume

density = m/V

density = 300 g / 200 cm³

density = 3/2 g/cm³

The lowest possible density of the material to make the paperweight would be $\frac{3}{2}$ g/cm²

The answer would be B, because since there are four quarts in a gallon, we take 1 and 1/2 and revert that back to quarts. That gives us 6. The graph clearly shows two, being B.
