13=10+3 so
13-7=3+10-7=3+3=6
The surface is the sun of all the sides. With the information provide I can only work out the volume, which is 420cm^3
Answer:
5/12 left
Step-by-step explanation:
1- you need to take 1/4 and 2/3 and find a common denominator, to find the exact amount of pounds.
2- Once you have 3/12 and 8/12, add them to get 11/12.
3-Now you know you don't have a full pound. Then subtract 1/2 from 11/12 ->
11/12 - 6/12 = 5/12
X = arctan(32/19)
x = 59.30 degrees.
You don't say if the answer needs to be rounded, so round it as needed.
