Are there any parentheses in the problem?
9 multiplied by 199 would be 1,791.
Given:
Dimension of box is 7 in, 13 in and 4 in.
To find:
Area of the smallest piece of paper
Solution:
Area of the rectangular box = length × width × height
= 7 × 13 × 4
Area of the rectangular box = 364 in³
Area of the rectangular box = Area of the gift paper to wrap the box
Therefore the area of the smallest piece of paper is 364 in³.
multiply the bottom then divide by the top
Answer:
3 * 10^6 if the answer is 3.64 * 10^6, you really ought to argue the meaning of estimate with your instructor.
Step-by-step explanation:
This is a very valuable question. Put your calculator away when you answer it. Using a calculator is sort of cheating.
1.3 * 10^3 roughly is roughly 1 * 10^3
2.8*10^3 hours is roughly 3 * 10^3
Forget the powers for now and just work with the 1 and 3
1*3 equals 3.
10^3 * 10^3 = 10^6 when the base of two numbers is the same (10 in this case) then the powers are added.
10^(3 + 3) = 10^6
So the answer is roughly 3*10^6
Now you can take out your calculator and get the answer.
1.3*10^3 * 2.8 * 10^3 = 3.64 * 10 ^ 6
Notice that the estimate (done in my head) is close enough to tell you what the answer should be. On a test, that's a very handy skill.
