Answer:
Volume =
cubic inches
Step-by-step explanation:
A cube is the 3D version of a square. Since one side length is x inches, all the other side lengths are same, x inches each.
We know,
Volume = area of base * height
THe base is a square and the area is side * side. We know each side is x, so we have:
Area of Square = Area of Base = x * x = 
Now, we know height is also same side length, x, thus the volume becomes:
Volume = area of base * height
Volume = 
We add the exponents when we have same base multiplied, so the expression for volume becomes:
Volume = 
Answer:
n=4
Step-by-step explanation:
Of means multiplying so,
×32=24
Multiply by n on both sides to get rid of the n denominator.
3×32=24n
Simplify the equation.
96=24n
Divide by 24.
n= 4

Answer:
20%
Step-by-step explanation:
Find the difference of both prices.
150 - 120 = 30
