2.45 is smaller.and thats it
Answer:
2. It will be a 7 3/4in x 12 1/4in rectangle
4. 31,987 in^2
6. 30 547/640 in^3
Step-by-step explanation:
2. This is a cross-section. In order to get the cross-section, you take your shape. (a 7 3/4 x 12 1/4 x 3 3/4 rectangle) and essentially you remove the last dimension (Height).
4. Take your surface area value (319 35/64) and multiply it by 100 (10 per dimension length and width). This leaves you with 319.87x100 = 31,987 in^2
6. (308 35/64)/10. Pretty easy, take 308.546875, divide by 10, and you get 30.8546875, which is 30 547/640 in^3 in fractions.
Ok so here it is
natural numbers: counting numbers like 1,2,3,4,5...
whole numbers: counting numbesr and 0, so 0,1,2,3,4
integers: negative counting numbers and 0, so -3,-2,-1,0,1,2,3...
ratioal numbers, things that can be represented in a/b
percent means parts out of 100 so
x%=x/100
that is a ratioal number
negatives are integers
