Answer:
305.25
Step-by-step explanation:
18.5 for one floor, multiply by 15 to get the amount for 15 floors: 18.5*15 = 277.5 sheets
We need to add 10% for waste, meaning 277.5 plus the waste: 1.1*277.5 = 305.25
Answer:
3m times 2m = 1m
Step-by-step explanation:
because 4m- 1 =3m and m+2 =2m

Answer:
D.
Step-by-step explanation:
D. This contains an x^2 and is called a parabola ( curved line like a U).
First find the radius of the sphere
V = 4/3 * pi * r^3
Givens
pi but we don't need it's value. We need only know it is on both sides of the equal sign.
V = 972 pi
Formula
V = 4/3 pi r^3
Sub and Solve
972 pi = 4/3 pi r^3 Divide both sides by pi. The 2 pis cancel each other out.
972 = 4/3 R^3 Multiply both sides by 3/4
3/4 * 972= 4/3 * 3/4 * r^3
3/4 * 972 = r^3
729 = r^3
cuberoot(729) = r
Box
r = 9 This is not the answer
d = 2*r
d = 2*9
d = 18
s = d (which is the side of the box
s = 18
V box = 18^3
Vbox = 5832 in^3
Pretty big isn't it?
