Unfortunately sucrose isn't classified as any of the above because it is not alive. Sucrose can however be classified as a disaccharide because it contains two monosaccharides (glucose and fructose). If you want to be more broad you can classify it as a carbohydrate.
Simply simplify multiplication expressions with a positive exponent
Answer:
6
Step-by-step explanation:
3 8s go in 24 so you multiply 2 pounds by 3 to get an equal ratio.
L=3W, H=2L, so H=6W
Since W=7, the dimensions would be:
W=7in, L=21in, H=42in
The surface area of any rectangular prism is:
A=2(LW+LH+WH), and since W=7, L=21, H=42
A=2(21*7+21*42+7*42)
A=2(147+882+294)
A=2(1323)
A=2646 in^2
The volume would be:
V=LWH, since L=21, W=7, H=42
V=21*7*42
V=6174 in^3
You question didn't really specify what you were looking for, so I did the best I could, if you need more info, just ask in the comments. :)
