Answer:

The largest  number of pyramids she can make from 20 bars of chocolate is:

  • <u>A. 180</u>

Step-by-step explanation:

Firstly, you must find the volume of the 20 bars of chocolate, remember that each bar contains 6 cubic inches of chocolate (6 in^3), so:

  • Volume of the bars = 6 in^3 * 20
  • <u>Volume of the bars = 120 in^3</u>

Now, you must find the volume of each pyramid, using the next formula:

  • Volume of a pyramid = 1/3 B * h

Where:

<em>B = area of the square base.</em>

<em>h = height of the pyramid.</em>

How these values are given in the problem, we only replace the values in the formula:

  • Area of a pyramid = 1/3 (1 in^2) * 2 in
  • <u>Area of a pyramid = 2/3 in^3</u>

Finally, we divide the volume of the bars in the volume of each pyramid:

  • Total number of pyramids = 120 in^3 / 2/3 in^3
  • <u>Total number of pyramids = 180</u>

svetoff [14.1K]
Your answer is correct, don't worry! To check your answer, just plug in the answer you got with the variable you are supposed to find. Multiplying by a half is like dividing by two. So, 16 divided by 2 is 8. 8 multiplied by 8.25 is 66. I'm jealous of your handwriting.. XD

Kisachek [45]
The easiest way is to use (& to memorize) the sum formula for a AP:


Sum = 1st term added to the last term & multiplied by half the number of terms
S = (a+l)n/2

S = (5 + 53)(7/2) = 203

JKL = NOP

We know the angles match

<J = <N

<K = <O

< L = <P

And we know

JK = NO

KL =  OP

JL = NP

We are looking for ON = KJ
