Question

For the upcoming holiday season, Dorothy wants to mold 20 bars of chocolate into tiny pyramids. Each bar of chocolate contains 6 cubic inches of chocolate. Dorothy plans to make chocolate pyramids with a square base of 1 square inch and a height of 2 inches. What is the largest number of pyramids she can make from the 20 bars of chocolate?.

Answer 1

Answer:

 180

Step-by-step explanation:

The volume of each pyramid is ...

  V = 1/3Bh

  V = 1/3(1 in²)(2 in) = 2/3 in³

The volume of chocolate Dorothy has to work with is ...

  (20 bars)×(6 in³/bar) = 120 in³

Then the number of pyramids she can make is ...

  (120 in³)/(2/3 in³/pyramid) = (120)(3/2) pyramids = 180 pyramids

Dorothy can make up to 180 pyramids from her 20 bars of chocolate.
