Answer:
The last guy's height is 69 inches
Step-by-step explanation:
mean=sum of all numbers/number of numbers
There are 5 numbers in the set which means that 65 is the sum of all five numbers divided by 5. To reverse that we multiply 65 by 5 to get the sum of all of the numbers.
325 is the sum of all of the numbers so to find the missing number you add up all of the known numbers in the set and find the difference between that sum and 325.
The missing guy's height is 69 inches.
Answer:
Step-by-step explanation:
At first, the question looks like an optimization problem, but since all the dimensions of the carton are given, we only have to compute the total area of the given figure.
Let's calculate the front (and back) areas, which are rectangles
Now with the lateral rectangles which happen to have the very same dimensions
Next, we compute the front and back triangles of base 3 in and height 1.5 in
Now, the lateral inclined rectangles of base 3 in and height 2 in
Finally, the base rectangle who happens to be a square of side 3 in
This last area, unlike all others, is not doubled because its counterpart is inside the carton and is not part of the lateral area
Our total area of cardboard is
