Answer:
Step-by-step explanation:
Q1, Reasonable lower limit for the number of M&M's can be done by using the rectangular prism volume formula = l*w*h
From the photo, there are about 8 M&Ms along its length, l and also 8 M&Ms along its width, w. Along height, h, there are about 14 stacking over each other.
So the number can be estimated as 8 * 8 * 14 = 896 ~1000
The answer is 1000.
Q2 Chocolate chip cookies:
First container is 11 * 6 * 3 = 198 cubic inches with 90 cookies
That gives an average of 198 / 90 = 2.2 cubic inches per cookie
Second container is 6 * 6 * 2 = 72 cubic inches with 33 cookies.
Again that gives an average of 72 / 33 = 2.2 cubic inches per cookie
The answer is 2.2.
Q3 Student numbers:
The first 4 characters are single digit number that cannot be repeated
So possible combinations are = 10 * 9 * 8 * 7
The last 2 characters are letters that cannot be repeated
So possible combinations are = 26 * 25
Total number of unique student numbers = 10 * 9 * 8 * 7 * 26 * 25
= 3,276,000
Q4 TV size goes by its diagonal
So it is sqrt(32^2 + 18^2)
= 37"
