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

The answer to the question is >
The sine of ∠I is represented by the ratio 63:65
Answer:
6
Step-by-step explanation:
The main idea of how to solve it is to isolate the variable. Whatever you multiply, divide, add, or subtract on one side, you must do the same to the other side so that both sides are equal.
3(x-1) = 21
3(x-1) / 3 = 21 / 3
x - 1 = 7
+ 1 + 1
x = 6
