If the side length is 5 x 2, 5 x 2 = 10, so 10 x 3 is 30. Hope this helped!

V = s³
V = (5x²)³
V = (5x²)(5x²)(5x²)
V = 5x²+²+²
V = 5x^6

Slope Formula: $\displaystyle m=\frac{y_2-y_1}{x_2-x_1}$

Step-by-step explanation:

Step 1: Define

Point (-2, -1)

Point (-8, 11)

Step 2: Find slope m

Simply plug in the 2 coordinates into the slope formula to find slope m

Substitute in points [Slope Formula]: $\displaystyle m=\frac{11+1}{-8+2}$
[Fraction] Add: $\displaystyle m=\frac{12}{-6}$
[Fraction] Divide: $\displaystyle m=-2$
