Answer: H
Step-by-step explanation:
We can see this rectangular prism will have side lengths of 5, 3, 7.
So we can use the fact Surface Area = 2(lh+wh+lw) to get:
2(15 + 35 + 21) = 2(71) = 142
Answer:

gallons of paint was used by Lucy.
Step-by-step explanation:

29/12 = 2 5/12
This is something to memorize
y = r*sin(theta)
so if y = 2, then
2 = r*sin(theta)
Divide both sides by sin(theta) to get
r = 2/sin(theta)
r = 2csc(theta)
37/3 ^2 = 1369/9
15/2 ^2 = 225/4
1369/9 + 225/4 = 7501/36
sqaureroot of 7501/36 = 14.43
so closest to B. 14 3/5
