The answer is 172.8 g.
The volume of the cube (V) is:
V = a³ (a - the side of the cube)
The density (D) <span>is quotient of mass (m) and volume (V):
D = m/V = m/a</span>³
⇒ m = D · a³
<span>
It is given:
D = 2.7 g/cm</span>³
a = 4 cm
Therefore:
m = D · a³ = 2.7 · 4³ = 172.8 g

Answer:
352 lbs is correct
Step-by-step explanation:
They did estimate correctly. for how to do this look below:
So we have a elephant that gains 22 pounds every week and they estimated that at 16 week she would be at 352 lbs
22 which was current pounds at the time and she would keep gaining that every week for 16 weeks
So weight times weeks
22*16
22*16= 352
Hope this helps!
Looking at the image I have attached (with MN being the midsegment of the trapezoid), For any PQ with P and Q lying on the bases of the trapezoid there exists ON with O being the point of intersection between PQ and MN. ON must be parallel to PC because ON is part of MN and PC is a part of DC, and MN and DC are parallel. And N must be the midpoint of CB because MN is the midsegment of the trapezoid, so MN must bisect CB. And since ON is parallel to PC and bisects CB, that means it is a midsegment of QBCP and must bisect PQ.
