A) 3 times 7x makes it a normal number of 21.
B) using PEMDAS you must multiply 5 times 5 to put 5 to its own power, then multiply by 2 to get 50, then add 4 getting 54.
C) 9 times 5y gets the normal number of 45, then subtract that from 80, you get 35.
The ratio of the Total surface area
is squared from the scale factor ratio.
So square root the total surface area ratio
1/2
So to get the ratio for volume, it’s cubed
Hence,
1/8
So 1/8 * 3200 = 400
