you can set it up as a proportion is (part) % ------- ------ of( whole) percent you fill in the spots so it looks like this. 70% is the percent, and the 210 as the of before it, so by default, the "is" becomes x. x 70 ------ ------ 210 100 then you cross multiply, so 100 times x is 100x and 210 times 70 is 14700. so, 100x=14700 then you have to get x by itself, to cancel out x you do the opposite of the opperation which in this case means to divide, so 100x/100 is x. but what you do to one side, you have to do to another, so 14700/100=147
so X=147, or 147 is 70% of 210 you can also check your answer by multiplying the "of" you get by the percent, and you should get the "is".

I am a cube that has a length ,width,and height of 1 unit
Answers
Surface area of the cube will be: 2 × area of base + perimeter of base × height of prism 2 × 1² + (1 × 4) × 1 2 + 4 6 units²
Volume will be: Area of base × Height of prism: 1² × 1 1³ 1 units³
The surface area is- a=l*w*h*6. The answer is 6. The volume would be v=l*w*h. Which equals 1. HTH
