Answer:
8.4in²
Step-by-step explanation:
We are given the dimensions of a box as :
7in = Height
6in = Length
2in = Width
The volume of a box = Length × Width × Height
Volume of a box = 7in × 6in × 2in
= 84in²
We are also told in the question to find the volume of the box if it is scaled down by a factor of 1/10
Hence,the new volume = 84in² × 1/10
= 8.4in²
Therefore, the volume of the box if it is scaled down by a factor of 1/10 is 8.4in²
I am sorry i have no idea. :( But i can ask my brother who is in a higher grade than i. i will ask him when he gets home for you. :)
Ok, make sure you put the powers correctly. I know what you mean but someone else may not. So it's step 2. This is because the 4 doesn't mean add a digit.
